                                     PART I

ITEM 1.  BUSINESS

         Allied Waste Industries, Inc., a Delaware corporation ("Allied" or the
"Company"), is a vertically-integrated, non-hazardous solid waste management
company providing collection, transfer, processing and disposal services. On
December 30, 1996, the Company completed the acquisition of substantially all of
the non-hazardous solid waste management business conducted by Laidlaw Inc.
("Laidlaw") in the United States and Canada (the "Laidlaw Acquisition"), for
total consideration of approximately $1.5 billion comprised of $1.2 billion
cash, 14.6 million shares of the Company's common stock, par value $0.01 per
share (the "Common Stock"), warrants to acquire 20.4 million shares of Common
Stock, and two junior subordinated debentures with an aggregate face amount of
$318 million (the "Allied Canada Debentures"). The cash consideration was
financed from the proceeds of a senior credit facility in the aggregate amount
of $1.275 billion (the "Senior Credit Facility") and the sale of $525 million of
the Company's 10 1/4% Senior Subordinated Notes due 2006 (the "1996 Notes").

         On March 16, 1997, pursuant to a Share Purchase Agreement with USA
Waste Services, Inc. ("USA Waste") the Company sold to USA Waste (the "Canadian
Sale") all of the Canadian non-hazardous solid waste management operations of
the Company for approximately $518 million. The Company used the proceeds from
the Canadian Sale to pay down approximately $517 million in debt under the
Senior Credit Facility. The Company acquired the Canadian operations in
connection with the Laidlaw Acquisition. Unless otherwise indicated, all
references to the Company and its operations contained herein give effect to the
Canadian Sale.

         The Company is the fourth largest solid waste management company in the
United States, as measured by revenues. The Company pursues a business strategy
designed to develop vertically-integrated operations centered around landfills
that are owned or operated by the Company in the markets it currently serves.
The Company serves 1.4 million customers through operations in 22 states located
primarily in the midwest, northeast, southeast and southwest United States. The
Company has an extensive network of 32 transfer stations, 46 landfills, and 20
recycling facilities.


INDUSTRY TRENDS

         According to the National Solid Waste Management Association and Waste
Age Magazine, the North American solid waste industry was estimated to have had
revenues of more than $32 billion in 1995. The industry is highly fragmented
with the four largest companies accounting, in 1995, for approximately 30% of
revenues, seven mid-sized public companies accounting for approximately 4% of
revenues, and several thousand municipalities and independent collection firms
accounting for the remainder. The solid waste management industry has been
affected significantly by increased regulation of disposal activities and to a
lesser extent collection activities also, have been affected. In October 1991,
the Environmental Protection Agency (the "EPA") adopted new regulations pursuant
to Subtitle D ("Subtitle D") of the Resource Conservation and Recovery Act of
1976, as amended ("RCRA") governing the disposal of non-hazardous solid waste.
These regulations led to a variety of requirements applicable to landfill
disposal sites, including the construction of liners and the installation of
leachate collection systems, groundwater monitoring systems and methane gas
recovery systems. The regulations also require enhanced control systems to
monitor more closely the waste streams being disposed at landfills, extensive
post-closure monitoring of sites and financial assurances that landfill
operators will be able to comply with the stringent regulations. The rising
costs associated with increasingly stringent industry regulations have tended to
promote consolidation and acquisition activity within the industry.


                                        2

<PAGE>   3
         The Company believes that these trends will continue and are the result
of several factors:

         (1)      Subtitle D and similar state regulations have significantly
                  increased the amount of capital and technical expertise
                  required to own and operate a landfill. As a result, many
                  landfill operators that lack the necessary capital or
                  expertise are electing to sell their landfills as an
                  alternative to closing them;

         (2)      a number of municipalities are electing to privatize their
                  municipal landfills as an alternative to funding the changes
                  to such landfills required by Subtitle D and related state
                  regulations; and

         (3)      as a result of heightened sensitivity to environmental
                  conditions in many communities, it is becoming increasingly
                  desirable for solid waste management companies to provide
                  waste recycling programs in addition to conventional
                  collection and disposal services.

These developments, as well as more stringent bonding requirements being imposed
on solid waste management companies by various municipalities, have increased
the amount of capital generally required for solid waste management operations,
causing smaller companies that lack the requisite capital to sell their
operations to better-capitalized companies.


BUSINESS STRATEGY

         The Company's business strategy is to build a vertically-integrated
solid waste management company with a strong presence in specific markets. The
Company plans to implement this strategy by (i) establishing a market presence
generally based on the acquisition or development of a landfill; (ii) increasing
volume in its markets through "tuck-in" acquisitions of collection companies and
marketing to new customers; (iii) providing a high level of customer service;
(iv) competitively pricing its services based on the particular circumstances of
each market; and (v) continuing to control costs and reduce corporate overhead
as a percentage of revenues. The Company believes that its strategy to build
vertically-integrated operations will provide the Company with competitive
advantages in its targeted regional markets.

         The Company pursues acquisitions in geographic areas characterized by
one or more of the following criteria: (i) the availability of permitted and
underutilized landfill capacity located either close to or outside of, but
within economic range of, a major population center, (ii) disposal fees that
justify necessary transportation expenses, (iii) near or medium-term scheduled
closures of landfills near such a population center, (iv) a shift in landfill
ownership from public to private and (v) rural landfills that are likely to
provide opportunities in a local market.

         The Company has adopted the following four-step program in executing
its business strategy:

         (1)      Landfill Acquisitions. Once the Company identifies an area
                  that qualifies under its target market criteria, the Company
                  seeks to establish a market presence, generally by acquiring
                  one or more landfills in that area that can be accessed
                  economically from the metropolitan center or from the regional
                  market area, either through direct hauling or through
                  strategically located transfer operations. In evaluating a
                  landfill acquisition, the Company considers, among others, the
                  following factors: (i) current disposal costs together with
                  transportation costs to the targeted landfill relative to
                  transportation and disposal costs of potential competitors,
                  (ii) expected landfill capacity, (iii) opportunities for
                  landfill expansion, and (iv) projected short-term ability to
                  secure an acceptable level of disposal volume.


                                        3

<PAGE>   4
         (2)      Secure Captive Waste Volumes. The Company seeks to build a
                  market presence and increase the utilization of the landfill
                  by securing captive waste streams, which includes developing
                  and acquiring transfer stations, entering into waste
                  collection contracts and acquiring waste collection companies.
                  Generally, the Company pursues the acquisition of collection
                  companies that: (i) have well-established residential or
                  commercial collection routes and accounts, (ii) own and
                  operate transfer stations, or (iii) do not own landfills and
                  are vulnerable to volatile disposal pricing, which the Company
                  believes it can minimize through landfill ownership.

         (3)      "Tuck-in" Acquisitions. The Company acquires service rights,
                  obligations, machinery and equipment in "tuck-in" acquisitions
                  of collection companies to: (i) increase the waste stream
                  directed to its landfills, (ii) maximize its market presence,
                  and (iii) increase customer density on collection routes to
                  reduce operating costs and strengthen return on capital.

         (4)      Integration of Operations. Immediately following an
                  acquisition, the Company begins to integrate the acquired
                  company into its operating and control systems, internalizing
                  waste previously disposed at third party landfills to
                  facilities owned or operated by the Company, establishing an
                  operating plan, implementing the Company's operating policies
                  and procedures, including the consolidation and
                  rationalization of routes and pricing, establishing new
                  banking and cash control procedures, integrating the acquired
                  company's accounting, data processing and management reporting
                  systems and appointing a new board of directors. In many
                  acquisitions, the Company retains the management of the
                  company it acquires in order to benefit from the existing
                  management's understanding of the local market, personal and
                  business contacts, and goodwill in the community.


OPERATIONS

         COLLECTION. Collection operations involve collecting and transporting
non-hazardous waste from the point of generation to the transfer station or the
site of disposal. Solid waste collection is generally provided under two primary
types of arrangements, depending on the customer being served.

         Commercial. The Company provides containerized non-hazardous solid
waste disposal services to a wide variety of commercial and industrial
customers. These customers are provided with containers that are designed to be
lifted mechanically and either emptied into a collection vehicle's compaction
hopper or, in the case of roll-off containers, to be loaded onto the collection
vehicle. The Company's commercial containers generally range in size from one to
eight cubic yards and its roll-off containers generally range in size from 20 to
40 cubic yards. Contracts for commercial containers typically have terms of up
to five years, may not be terminated by the customer prior to the end of the
term and have renewal options. Contracts for roll-off containers may provide for
temporary (such as the removal of waste from a construction site) or ongoing
services. Fees relating to those contracts are determined by general competitive
and prevailing local economic conditions and include other considerations such
as collection frequency, type of equipment furnished, distance traveled to the
disposal site, the cost of disposal and the type and volume or weight of the
waste collected.

         Residential. Residential collection services are performed pursuant to
individual monthly subscriptions directly to households or long-term contracts
with municipal governments that give the Company exclusive rights to service all
or a portion of the homes in such municipalities at established rates. The
Company seeks to obtain municipal contracts which enhance the efficiency and
profitability of the Company's operations as a result of the density of
collection customers within a given area. At the end of the term of most
municipal contracts, the Company will attempt to renegotiate the contract, and
if unable to do so, will rebid the contract on a sealed bid basis. Residential
collection service arrangements with households are made directly between the
Company and the resident. The Company seeks to enter into residential service
arrangements where the route density is high, thereby creating additional
economic benefit. Collection fees are determined by the Company and the customer
based on general competitive and prevailing local economic conditions and
include other considerations such as collection


                                        4

<PAGE>   5
frequency, the type and volume or weight of the waste collected, the distance to
the disposal facility, and cost of disposal. Residential collection fees are
either paid by the municipalities out of tax revenues or service charges or are
paid directly by the residents who receive the service.

         TRANSFER STATIONS. A transfer station is a facility where solid waste
is received from third-party and Company owned collection vehicles and then
transferred to and compacted in large, specially-constructed trailers for
transportation to disposal facilities. This consolidation reduces costs by
increasing the density of the waste being transported through competition and by
improving utilization of collection personnel and equipment, and is an
increasingly common procedure in the solid waste management industry. Fees are
generally based upon such factors as the type and volume or weight of the waste
transferred and the transport distance involved. The Company believes that as
increased regulations and public pressure restrict the development of landfills
in urban and suburban areas, transfer stations will increasingly be used as an
efficient means to transport waste over longer distances to available landfills.

         RECYCLING. In response to increasing awareness by the customer of
environmental concerns and expanding federal and state regulations pertaining to
waste recycling, the Company includes recycling as a component of its vertically
integrated solid waste business strategy. Services include curbside collection
of recyclable materials for residential customers, commercial and industrial
collection of recyclable materials, and, to a lesser extent, material
recovery/waste reduction. Recycling fees are generally service based wherein the
customer pays for the cost of removing, processing and disposing of potentially
recyclable materials. In most cases, mixed waste materials are received at an
owned or leased materials recovery facility ("MRF") which is often integrated
into or contiguous to a transfer operation. Materials such as paper, cardboard,
plastic, aluminum and other metals are sorted, separated, accumulated, bound or
placed in a container and readied for transportation to a third-party which will
reuse the separated materials. The purchaser generally pays for the materials
based on fluctuating spot-market prices. Material for which there is no market
or for which the market price is insufficient to warrant processing are disposed
of at a landfill or other disposal facility. The Company seeks to avoid exposure
to fluctuating commodity prices by passing through substantially all of the
profit or loss from the sale of recyclables to its service customers.

         LANDFILLS. Solid waste landfills are the primary method of disposal of
solid waste in the United States. Currently, a landfill must be designed,
permitted, operated and closed in compliance with federal, state and local
regulations pursuant to Subtitle D. Operating procedures include excavation,
continuous spreading and compacting of waste, and covering of waste with earth
or other inert material. The cost of transferring solid waste to a disposal
location places an economic restriction on the geographic scope of landfill
operations in a particular market. Access to a disposal facility, such as a
landfill, is a requirement for all solid waste management companies. While
access can generally be obtained to disposal facilities owned or operated by
unaffiliated parties, the Company believes that, in keeping with its business
strategy, it is preferable for collection companies to own or operate their own
disposal facilities thereby ensuring access on favorable terms and the
internalization of disposal fees.


MARKETING AND SALES

         Each of the Company's districts has a staff responsible for sales and
marketing. The Company's policy is to periodically visit each commercial account
to ensure customer satisfaction and to sell additional services. In addition to
calling on existing customers, each salesperson calls upon potential customers
within a defined area in each market.

         In addition to its sales efforts directed at commercial and industrial
customers, the Company has a municipal marketing coordinator in most service
areas. The municipal marketing coordinators are responsible for interfacing with
each municipality or community to which the Company provides residential service
to assure customer satisfaction. In addition, the municipal coordinators
organize and handle bids for renewal and new municipal contracts in their
service area.


                                        5

<PAGE>   6
COMPETITION

         The non-hazardous waste collection and disposal industry is highly
competitive. The industry is comprised of four national waste companies in
addition to the Company, WMX Technologies, Inc., Browning-Ferris Industries,
Inc. ("BFI"), Republic Industries, Inc., USA Waste Services, Inc. and local and
regional companies of varying sizes and competitive resources such as United
Waste Systems, Inc. and Superior Services, Inc. The Company also competes with
those counties and municipalities that maintain their own waste collection or
disposal operations. These counties and municipalities may have financial
advantages through their access to tax revenues and tax-exempt financing and
their ability to mandate the disposal of waste collected within the jurisdiction
at a municipal landfill. The Company may also experience competition from
companies using alternative methods of managing solid waste streams, such as
incineration.

         The solid waste collection and disposal industry is currently
undergoing significant consolidation, and the Company encounters competition in
its efforts to acquire landfills and collection operations. Accordingly, it may
become uneconomical for the Company to make further acquisitions or the Company
may be unable to locate or acquire suitable acquisition candidates at price
levels and on terms and conditions that the Company considers appropriate,
particularly in markets the Company does not already serve.


ENVIRONMENTAL AND OTHER REGULATIONS

         The Company is subject to extensive and evolving environmental laws and
regulations. These regulations are administered by the EPA and various other
federal, state and local environmental, zoning, health and safety agencies, many
of which periodically examine the Company's operations to monitor compliance
with such laws and regulations. The Company believes that there will be
increased regulation and legislation related to the waste management industry
and the Company attempts to anticipate such future regulatory requirements to
ensure compliance.

         The Company's operation of landfills subjects it to certain
operational, monitoring, site maintenance, closure, post-closure and other
obligations which could give rise to increased costs for monitoring and
corrective measures. In connection with the Company's acquisition of existing
landfills, it is often necessary to expend considerable time, effort and money
to obtain permits required to increase the capacity of these landfills.
Governmental authorities have the power to enforce compliance with these
regulations and to obtain injunctions or impose civil or criminal penalties in
case of violations. The Company cannot predict whether or not it will be able to
obtain the governmental approvals necessary to establish new or expand existing
landfills and, if it does, whether or not it will be economically beneficial to
do so.

         The Company's operations are subject to extensive regulation,
principally under the following federal statutes:

         The Resource Conservation and Recovery Act of 1976, as amended. RCRA
regulates the handling, transportation and disposal of hazardous and
non-hazardous wastes and delegates authority to states to develop programs to
ensure the safe disposal of solid wastes. On October 9, 1991, the EPA
promulgated Solid Waste Disposal Facility Criteria for non-hazardous solid waste
landfills under Subtitle D. Subtitle D includes location standards, facility
design and operating criteria, closure and post-closure requirements, financial
assurance standards and groundwater monitoring as well as corrective action
standards, many of which had not commonly been in place or enforced previously
at landfills. Subtitle D applies to all solid waste landfill cells that received
waste after October 9, 1991, and, with limited exceptions, all landfills were
required to meet these requirements by October 9, 1993. Landfills that were not
in compliance with the requirements of Subtitle D on the applicable date of
implementation were required to close. In addition, landfills that stopped
receiving waste before October 9, 1993 were not required to comply with the
final cover provisions of Subtitle D. Each state must comply with Subtitle D and
was required to submit a permit program designed to implement Subtitle D to the
EPA for approval by April 9, 1993. States may impose requirements for


                                        6

<PAGE>   7
landfill units that are more stringent than the requirements of Subtitle D. Once
a state has an approved program, it must review all existing landfill permits to
ensure that they comply with Subtitle D.

         The Federal Water Pollution Control Act of 1972 (the "Clean Water
Act"), as amended. This act establishes rules regulating the discharge of
pollutants into streams and other waters of the United States (as defined in the
Clean Water Act) from a variety of sources, including solid waste disposal
sites. If runoff from the Company's landfills or transfer stations may be
discharged into surface waters, the Clean Water Act requires the Company to
apply for and obtain discharge permits, conduct sampling and monitoring and,
under certain circumstances, reduce the quantity of pollutants in those
discharges. The permit program has been expanded to include stormwater
discharges from landfills that receive, or in the past received, industrial
waste. In addition, if development may alter or affect "wetlands," a permit may
have to be obtained and certain mitigation measures may need to be undertaken
before such development may be commenced. This requirement is likely to affect
the construction or expansion of many solid waste disposal sites, including some
owned or being developed by the Company. The Clean Water Act provides civil,
criminal and administrative penalties for violations of its provisions.

         The Comprehensive Environmental Response, Compensation and Liability
Act of 1980, as amended. The Comprehensive Environmental Response, Compensation
and Liability Act of 1980, as amended ("CERCLA") addresses problems created by
the release or threatened release of hazardous substances into the environment.
CERCLA's primary mechanism for remediating such problems is to impose strict,
joint and several liability for cleanup of disposal sites on current owners and
operators of the site, former site owners and operators at the time of disposal,
and waste generators and parties who arranged for disposal at the facility. The
costs of a CERCLA cleanup can be substantial. Liability under CERCLA is not
dependent on the existence or disposal of "hazardous wastes" (as defined under
RCRA), but can also be founded on the existence of even minute amounts of the
more than 700 "hazardous substances" listed by the EPA.

         The Clean Air Act of 1970 (the "Clean Air Act"), as amended. The Clean
Air Act provides for increased federal, state and local regulation of the
emission of air pollutants. The EPA has construed the Clean Air Act to apply to
landfills. In March 1996, the EPA adopted New Source Performance Standard and
Emission Guidelines (the "Emission Guidelines") for municipal solid waste
landfills. These regulations impose limits on air emissions from solid waste
landfills. The Emission Guidelines propose two sets of emissions standards, one
of which is applicable to all solid waste landfills that commence construction,
reconstruction or modification after May 30, 1991 and another which is
applicable to all solid waste landfills that received waste or had the capacity
to receive waste after November 8, 1987. The Emission Guidelines may be
implemented by the states. These guidelines, combined with the new permitting
programs established under the recent Clean Air Act amendments, will likely
subject solid waste landfills to significant new permitting requirements and, in
some instances, require installation of methane gas recovery systems.

         The Occupational Safety and Health Act of 1970 ("OSHA"), as amended.
OSHA establishes certain employer responsibilities, including maintenance of a
workplace free of recognized hazards likely to cause death or serious injury,
compliance with standards promulgated by the Occupational Safety and Health
Administration, and various recordkeeping, disclosure and procedural
requirements. Various standards, including standards for notices of hazards,
safety in excavation and demolition work, and the handling of asbestos, may
apply to the Company's operations.

         Future Federal Legislation. In the future, the Company's collection,
transfer and landfill operations may also be affected by legislation that may be
proposed in the United States Congress that would authorize the states to enact
legislation governing interstate shipments of waste. Such proposed federal
legislation may allow individual states to prohibit the disposal of out-of-state
waste or to limit the amount of out-of-state waste that could be imported for
disposal and would require states, under certain circumstances, to reduce the
amounts of waste exported to other states. If this or similar legislation is
enacted, states in which the Company will operate landfills could act to limit
or prohibit the importation of out-of-state waste. Such state actions could
adversely affect landfills within these states that receive a significant
portion of waste originating from out-of-state.


                                        7

         State Regulation. Each state in which the Company operates has laws and
regulations governing solid waste disposal and water and air pollution and, in
most cases, regulations governing the design, operation, maintenance and closure
of landfills and transfer stations. Management believes that several states have
proposed or have considered adopting legislation that would regulate the
interstate transportation and disposal of waste in their landfills. Many states
have also adopted legislative and regulatory measures to mandate or encourage
waste reduction at the source and waste recycling.

         The Company's collection and landfill operations may be affected by the
current trend toward laws requiring the development of waste reduction and
recycling programs. For example, a number of states have recently enacted laws
that will require counties to adopt comprehensive plans to reduce, through waste
planning, composting and recycling or other programs, the volume of solid waste
deposited in landfills within the next few years. A number of states have also
taken or propose to take steps to ban or otherwise limit the disposal of certain
wastes, such as yard wastes, beverage containers, newspapers, unshredded tires,
lead-acid batteries and household appliances into landfills.

         The Company has implemented and will continue to implement its own
environmental safeguards that comply with or exceed these governmental
requirements. Additionally, the Company's policy will be to obtain an
environmental assessment prepared by an independent environmental consulting
firm for all real estate acquired.


LIABILITY INSURANCE AND BONDING

         The Company carries general liability, comprehensive property damage,
workers' compensation, employer's liability, directors' and officers' liability
and other coverages it believes are customary to the industry. The Company also
has environmental impairment liability insurance for all of its operating
landfills except one owned and four operated sites. The environmental impairment
liability insurance is in the amount of up to $5 million for the policy term in
excess of a $1 million deductible per claim. Except as discussed in Legal
Proceedings below, management does not expect the impact of any known
environmental or other contingencies to be material to the Company's
consolidated liquidity, financial position or results of operations.

         The Company is required to provide certain financial assurances to
governmental agencies under applicable environmental regulations relating to its
landfill and collection operations. These financial assurances include
performance bonds, letters-of-credit, insurance contracts and trust deposits
required principally to secure the Company's estimated landfill closure and
post-closure obligations and collection contracts. The Company expects to be
required to provide approximately $227.6 million in financial assurance
obligations relating to its landfill operations by the end of fiscal year 1997.
The Company expects that financial assurances will increase in the future as the
Company acquires and expands its activities and that a greater percentage of the
financial assurances will be comprised, directly and indirectly, of
letters-of-credit.


EMPLOYEES

         The Company employs approximately 5,000 persons. Certain employees of
the Company are covered by collective bargaining agreements. The Company
believes relations with its employees are satisfactory.


ITEM 2.  PROPERTIES

         The Company's principal executive offices are located at 15880
Greenway-Hayden Loop, Suite 100, Scottsdale, Arizona 85260 where it currently
leases 33,000 square feet of office space. The Company also maintains six
regional administrative offices in the United States.


                                        8

<PAGE>   9
         The principal fixed assets used by the Company in its collection and
transfer operations are 32 owned or operated transfer/recycling facilities. The
Company operates 46 non-hazardous solid waste landfills.


ITEM 3.  LEGAL PROCEEDINGS

         The Company is currently involved in certain routine litigation. The
Company believes that all such litigation arose in the ordinary course of
business and that costs of settlements or judgments arising from such suits will
not have a materially adverse effect on the Company's consolidated liquidity
financial position or results of operations.

         The business of the Company is regulated by federal, state and local
provisions that relate to the protection of the environment. The nature of the
Company's business results in it frequently becoming a party to judicial or
administrative proceedings involving governmental authorities and other
interested parties. At December 31, 1996, the Company was not involved in any
such proceedings where management believes sanctions imposed by governmental
authorities may exceed $100,000. From time to time the Company may also be
subject to actions brought by citizens' groups, adjacent landowners or others in
connection with the permitting and licensing of its landfills or transfer
stations, or alleging personal injury, environmental damage or violations of the
permits and licenses pursuant to which the Company operates.

         In connection with the Laidlaw Acquisition, Allied engaged an
independent environmental consulting firm to assist in conducting an
environmental assessment of the real property owned by certain subsidiaries of
the Company acquired from Laidlaw (the "LWS Subsidiaries") or third-parties, and
properties under the management of the LWS Subsidiaries. Several contaminated
landfills and other properties have been identified, two of which are owned by
subsidiaries of the Company, that would require those subsidiaries to incur
costs for incremental closure and post-closure measures, remediation activities
and litigation costs in the future. The costs of performing the investigation,
design, remediation and allocation of responsibility to the subsidiaries of
Allied vary significantly between sites. Based on information available to the
Company, Allied recorded a provision of $51.5 million for environmental matters,
including closure and post-closure costs, in the 1996 statement of operations
and expects these amounts to be disbursed over the next 30 years.

         The Company has been notified that it is considered a potentially
responsible party at a number of locations under CERCLA or other environmental
laws. The Company continually reviews its status with respect to each location,
taking into account the alleged connection to the location and the extent of the
contribution to the volume of waste at the location, the available evidence
connecting the entity to that location and the numbers and financial soundness
of other potentially responsible parties at the location. The ultimate amounts
for environmental liabilities at sites regarding which the Company may be a
potentially responsible party cannot be determined and estimates of such
liabilities made by the Company, after consultation with its independent
environmental engineers, require assumptions about future events due to a number
of uncertainties including the extent of the contamination, the appropriate
remedy, the financial viability of other potentially responsible parties and the
final apportionment of responsibility among the potentially responsible parties.
Where the Company has concluded that its estimated share of potential
liabilities is probable, a provision has been made in the consolidated financial
statements. Since the ultimate outcome of these matters may differ from the
estimates used in the Company's assessment to date, the recorded liabilities
will be periodically evaluated as additional information becomes available to
ascertain that the accrued liabilities are adequate. The Company has determined
that the recorded liability for environmental matters as of December 31, 1996 of
approximately $152.5 million (including the $51.5 million provision charged to
the 1996 statement of operations) represents the most probable outcome of these
contingent matters. The Company does not expect that adjustments to estimates,
which are reasonably possible in the near term and that may result in changes to
recorded amounts, will have a material effect on the Company's consolidated
liquidity, financial position or results of operations.

         The consolidated federal income tax returns for the fiscal years ended
August 31, 1986, 1987 and 1988 of certain subsidiaries of the Company that were
acquired from Laidlaw in December 1996 have been under audit by the Internal
Revenue Service. In March 1994, the LSW Subsidiaries received a Statutory Notice
of Deficiency proposing that the LSW Subsidiaries pay additional taxes relating
to disallowed deductions in those income tax returns (the "Tax Controversy").
The consolidated tax group of the LSW Subsidiaries has also received notice that
fiscal years 1992, 1993 and 1994 will be examined regarding the Tax Controversy.
The LSW Subsidiaries could be directly liable for a substantial portion of any
tax and interest assessed if the disallowance of the deduction is sustained. In
addition, under Treasury Regulations promulgated under Section 1502 of the
Internal Revenue Code ("IRC"), each member of the consolidated tax group
including each LSW Subsidiary, is or could be severally liable for federal
income tax liabilities of the entire consolidated tax group, including any taxes
due on the deemed sale of assets by the LSW Subsidiaries pursuant to Section 338
of the IRC and all amounts at issue in the Tax Controversy which are ultimately
determined to be owed.

         Any amounts at issue in the Tax Controversy and for which any LSW
Subsidiary may ultimately be found liable, are included in and covered by the
indemnification of the Company by Laidlaw set forth in the Stock Purchase
Agreement by and between the Company and Laidlaw, among others, dated September
17, 1996 (the "Purchase Agreement"). Further, the Company and Laidlaw, among
others, have entered into a Setoff Agreement, under which Laidlaw has agreed
that if the Tax Controversy results in any damage, liability or expense to any
LSW Subsidiary, and if Laidlaw fails to indemnify the Company against all such
damages, liabilities or expenses within 30 days of a demand for indemnification,
then the Company may setoff the amount of all such damages, liabilities and
expenses against all amounts then owed by the Company under the certain debt
issued to Laidlaw consisting primarily of the Allied Canada Debentures.

         Other than to the extent contemplated in the Setoff Agreement, the
obligation of Laidlaw to indemnify the Company in respect of amounts at issue in
the Tax Controversy is a general, unsecured obligation of Laidlaw. The ability
of Laidlaw to pay and fulfill such indemnification obligation will depend on the
financial condition of Laidlaw at the time of any required performance of such
obligation.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

         The following discussion should be read in conjunction with the
Company's Consolidated Financial Statements and the notes thereto, included
elsewhere herein.


INTRODUCTION

         The Company has experienced significant growth, a substantial portion
of which has resulted from the acquisition of solid waste businesses. Since
January 1, 1992, the Company has completed 96 acquisitions including the Laidlaw
Acquisition. In 1996, the Company acquired 22 businesses including the Laidlaw
Acquisition and subsequent to 1996 it has acquired 2 businesses. See Note 2 to
the Company's Consolidated Financial Statements. The Company's Consolidated
Financial Statements have been restated to reflect the acquisition of companies
accounted for using the pooling-of-interests method for business combinations.
The majority of the acquisitions were accounted for under the purchase method
for business combinations and, accordingly, the results of operations for such
acquired businesses are included in the Company's financial statements only from
the applicable date of acquisition. As a result, the Company believes its
historical results of operations for the periods presented are not directly
comparable.

         On December 30, 1996, the Company completed the acquisition of
substantially all of the non-hazardous solid waste management business conducted
by Laidlaw in the United States and Canada, for total consideration of
approximately $1.5 billion comprised of $1.2 billion cash, 14.6 million shares
of Common Stock, warrants to acquire 20.4 million shares of Common Stock, and
two junior subordinated debentures with an aggregate face amount of $318
million. The cash consideration was financed from the proceeds of the Senior
Credit Facility and the sale of the 1996 Notes.

         On March 16, 1997, pursuant to a Share Purchase Agreement with USA
Waste, the Company sold to USA Waste all of the Canadian non-hazardous solid
waste management operations of the Company for approximately $518 million. The
Company used the proceeds from the Canadian Sale to pay down approximately $517
million in debt under the Senior Credit Facility. The Company acquired the
Canadian operations in connection with the Laidlaw Acquisition.


GENERAL

         Revenues. The Company's revenues are attributable primarily to fees
charged to customers for waste collection, transfer, recycling and disposal
services. The Company's collection services are generally provided under direct
agreements with its customers or pursuant to contracts with municipalities.
Commercial and municipal contract terms, where used, generally range from 1 to 5
years and commonly have automatic renewal options. The Company's landfill
operations include both Company-owned landfills and those operated for
municipalities for a fee. The Company is fully integrated in each geographic
region in which it is located as it provides collection, transfer and disposal
services. The tables below show for the periods indicated the percentage of the
Company's total reported revenues attributable to services provided and to
geographic region:

- ------------------

(1)      The portion of collection revenues attributable to disposal charges for
         waste collected by the Company and disposed at the Company's landfills
         have been excluded from collection revenues and included in landfill
         revenues.

         The Company's strategy is to develop vertically integrated operations
to ensure internalization of waste it collects and thus realize higher margins
from its operations. By disposing of waste at Company-owned and/or operated
landfills, the Company retains the margin generated through disposal operations
that would otherwise be earned by third-party landfills. Approximately 71% of
Company-collected waste is disposed of at Company-owned and/or operated
landfills as measured using disposal costs in 1996. After taking into account
the Laidlaw Acquisition, this measure is expected to be approximately 60%. In
addition, transfer stations are an integral part of the disposal process. The
Company locates its transfer stations in areas where its landfills are outside
of the population centers in which it collects waste. Such waste is transloaded
and economically transported to its landfills. Transfer and landfill revenues as
a percentage of total revenues increased from 8.4% and 14.5% in 1994 to 8.5% and
22% in 1996, respectively, which reflects the continued implementation of the
Company's strategy.

         Expenses. Cost of operations includes labor, maintenance and repairs,
equipment and facility rent, utilities and taxes, the costs of ongoing
environmental compliance, safety and insurance, disposal costs and costs of
independent haulers transporting Company waste to the disposal site. Disposal
costs include certain landfill taxes, host community fees, payments under
agreements with respect to landfill sites that are not owned, landfill site
maintenance, fuel and other equipment operating expenses and accruals for
estimated closure and post-closure monitoring expenses anticipated to be
incurred in the future.

         Selling, general and administrative expenses include management,
clerical and administrative compensation and overhead, sales costs, community
relations expenses and provisions for estimated uncollectible accounts
receivable and potentially unrealizable acquisition costs.

         Depreciation and amortization expense includes depreciation of fixed
assets and amortization of landfill airspace, goodwill and other intangible
assets.

         In connection with potential acquisitions, the Company incurs and
capitalizes certain transaction and integration costs which include stock
registration, legal, accounting, consulting, engineering and other direct costs.
When an acquisition is completed and is accounted for using the
pooling-of-interests method for business combinations, these costs are charged
to the statement of operations as acquisition related costs. When a completed
acquisition is accounted for using the purchase method for business
combinations, these costs are capitalized. The Company routinely evaluates
capitalized transaction and integration costs and expenses those costs related
to acquisitions not likely to occur. Indirect acquisition costs, such as
executive salaries, general corporate overhead and other corporate services, are
expensed as incurred.

         Certain direct landfill development costs, such as engineering,
upgrading, construction and permitting costs, are capitalized and amortized
based on consumed airspace. The Company believes that the costs associated with
engineering, owning and operating landfills will increase in the future as a
result of federal, state and local regulation and a growing community awareness
of the landfill permitting process. Although there can be no assurance, the
Company believes that it will be able to implement price increases sufficient to
offset these increased expenses. All indirect landfill development costs, such
as executive salaries, general corporate overhead, public affairs and other
corporate services, are expensed as incurred.

<PAGE>   18
         Accrued closure and post-closure costs represent an estimate of the
current value of the future obligation associated with closure and post-closure
monitoring of non-hazardous solid waste landfills currently owned and/or
operated by the Company. Site specific closure and post-closure engineering cost
estimates are prepared annually for landfills owned and/or operated by the
Company for which it is responsible for closure and post-closure. The present
value of estimated future costs are accrued based on accepted tonnage as
landfill airspace is consumed. Discounting of future costs is applied where the
Company believes that both the amounts and timing of related payments are
reliably determinable. The Company periodically updates its estimates of future
closure and post-closure costs. The impact of changes which are determined to be
changes in estimates are accounted for on a prospective basis.

         The net present value of the closure and post-closure commitment is
calculated assuming inflation of 3.5% and a risk-free capital rate of 7.0%.
Discounted amounts previously recorded are accreted to reflect the effects of
the passage of time. The Company's current estimate of total future payments for
closure and post-closure is $467 million while the present value of such
estimate is $181 million. At December 31, 1995 and 1996, accruals for landfill
closure and post-closure costs (including costs assumed through acquisitions)
were approximately $10.5 million and $107.5 million. The accruals reflect
relatively young landfills with estimated remaining lives, based on current
waste flows, that range from 1 to over 75 years, and an estimated average
remaining life of greater than 30 years.

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 1996 AND 1995

         Revenues. Revenues in 1996 were $246.7 million compared to $217.5
million in 1995, an increase of 13.4%. Approximately 4.3% of the increase in
revenues is attributable to acquisitions and 9.1% is attributable to internal
growth. Revenues of $9.4 million for 1996 were generated from companies acquired
subsequent to December 1994, while increases in revenue attributable to existing
operations amounted to $19.8 million. Average price increases as a percentage of
revenue were approximately 3% of revenue while the remainder of internal growth
was from volume.

         Cost of Operations. Cost of operations in 1996 was $138.4 million
compared to $120.7 million in 1995, an increase of 14.7%. This increase in cost
of operations was primarily attributable to the increase in revenues described
above. As a percentage of revenues, cost of operations increased to 56.1% in
1996 from 55.5% in 1995. Operating costs were affected by an increase in the
percentage of waste internalized to 71% in 1996 from 62% in 1995 which resulted
in a decrease in third-party disposal costs as a percent of revenue. Cost of
operations were also effected by a significant increase in municipal solid waste
volumes offset by a decrease in higher priced special waste volumes. This change
in revenue mix had the effect of increasing the cost of disposal relative to
revenues.

         Selling, General and Administrative Expenses. SG&A expenses increased
to $38.6 million in 1996 compared to $36.7 million in 1995, an increase of 5.2%.
As a percentage of revenues, SG&A decreased to 15.6% in 1996 from 16.9% in 1995.
The increase in SG&A expense resulted from expenses associated with acquired
companies and expenses incurred in connection with the Company's increase in
personnel and other expenses related to the anticipated growth of the Company as
it continues to acquire companies. The decrease in SG&A as a percentage of
revenues can be attributed to an increase in revenue producing assets while
corporate level personnel and other related expenses increased moderately.

         Depreciation and Amortization Expense. Depreciation and amortization in
1996 was $31.5 million compared to $25.8 million in 1995, an increase of 22.1%.
The increase in depreciation and amortization expense is due to acquisitions and
capital expenditures. Before the Laidlaw Acquisition, fixed assets increased to
$442.2 million at December 31, 1996 from $366.6 million at December 31, 1995 and
goodwill increased to $110.7 million at December 31, 1996 from $98.1 million at
December 31, 1995. As a percentage of revenues, depreciation and amortization
increased to 12.8% in 1996 from 11.9% in 1995. This increase is primarily
because amortization of landfill airspace as a percentage of revenue increased
to 3.2% in 1996 from 2.7% in 1995 resulting from an increase in the rate of
waste internalization.

         Acquisition Related Costs. In connection with the Laidlaw Acquisition,
the Company incurred approximately $84.6 million in charges primarily associated
with the acquisition, which include $51.5 million of environmental related
matters, $18.4 million of asset impairments and abandonments, and $14.7 million
of acquisition liabilities, of which $2.0 million relates to litigation matters,
$5.4 million relates to relocation and transition costs and bonuses, $3.8
million relates to taxes, claims and assessments and other integration costs,
and $3.5 million relates to acquired accounts receivable considered
uncollectible.

         In connection with the Laidlaw Acquisition, Allied engaged an
independent environmental consulting firm to assist in conducting an
environmental assessment of the real property owned by the acquired subsidiaries
or third-parties, and properties under the management of the acquired companies.
Several contaminated landfills and other properties have been identified, two of
which are owned by subsidiaries of the Company, that would require those
subsidiaries to incur costs for incremental closure and post-closure measures,
remediation activities and litigation in the future. The costs of performing the
investigation, design, remediation and the allocation of responsibility to the
subsidiaries of Allied vary significantly between sites. Based on information
available to the Company, Allied recorded a provision of $51.5 million for
environmental matters, including closure and post-closure costs, in the 1996
statement of operations and expects these amounts to be disbursed over the next
30 years.


                                       19

<PAGE>   20
         As a result of the Laidlaw Acquisition, Allied increased its revenue
base by approximately 400% and entered into 14 new markets where it believes
that it can execute its operating strategy. In connection with the significant
increase in size and the redirection of its strategic operating emphasis, Allied
determined that certain asset values have become impaired as they will provide
no further benefit to Company. Included among the asset impairments are costs of
$10.8 million related to over 50 noncompetition agreements in several markets
where the counterparty no longer poses a significant threat, costs of $4.8
million for discontinued facilities and costs of $2.8 million for market
development activities no longer being pursued.

         Costs of $7.1 million were incurred in 1996 compared to $1.5 million in
1995 for transaction and integration costs directly related to acquisitions
accounted for using the pooling-of-interests method for business combinations.

         Unusual Items. In December 1996 the Company recorded $5.7 million in
unusual items including $2.0 million in connection with the ongoing
investigation and remediation of the Company's Norfolk landfill and $3.7 million
of other non-recurring valuation adjustments.

         Net Interest Expense. Net interest expense was $7.1 million in 1996
compared to $10.6 million in 1995, a decrease of 32.9%. The decrease in net
interest expense is partially due to the conversion of subordinated debt into
Common Stock in the fourth quarter of 1995 which resulted in a reduction to
annual interest charges and the refinancing of the 1994 Notes (as defined
herein) on July 31, 1996 resulting in a decrease in the interest rate from 12%
to 7% for the months of August through December 1996. Also, interest capitalized
in 1996 was $13.0 million compared to $11.1 million in 1995.

         Conversion Fees. A non-cash conversion fee of $2.2 million was incurred
in the fourth quarter of 1995 as a result of an inducement offered by the
Company to holders of certain convertible preferred stock and convertible
subordinated notes to exercise their conversion option to receive Common Stock.
The inducement fee consisted of payment of dividends or interest from the
conversion date through the first call or redemption date of each convertible
security. Approximately 7.8 million shares of Common Stock were issued for
conversion and approximately 285,000 were issued for the conversion fee.

         Income Taxes. Income taxes reflect a benefit at a 0.6% effective income
tax rate for 1996 which deviates from the federal statutory rate of 35% due
primarily to the treatment of expenses for book purposes that, when recognized
for tax purposes, may produce tax goodwill in excess of book goodwill. Other
items impacting the Company's effective tax rate for both 1996 and 1995 include
the differences in the treatment of goodwill for book and tax purposes, state
income taxes, and other permanent differences. See Note 10 to the Consolidated
Financial Statements.

         Extraordinary Loss. On July 31, 1996, Allied completed a tender offer
(the "Tender Offer") for substantially all of the 1994 Notes at the redemption
price of $1,157.50 per $1,000 note. An extraordinary charge related to the
Tender Offer of approximately $18.4 million ($11.0 million net of income tax
benefit), was charged to earnings in the third quarter of 1996. In connection
with the Laidlaw Acquisition, the Company refinanced its $300 million senior
revolving credit facility and recognized an extraordinary charge of
approximately $4.0 million ($2.4 million net of income tax benefit) was charged
to earnings in the fourth quarter of 1996.

YEARS ENDED DECEMBER 31, 1995 AND 1994

         Revenues. Revenues in 1995 were $217.5 million compared to $158.4
million in 1994, an increase of 37.4%. The increase in revenues is due primarily
to the effects of acquisitions as well as price and volume increases
attributable to existing operations. Revenues of $34.4 million in 1995 were
generated from companies acquired since January 1994, while increases in
revenues attributable to existing operations amounted to $24.7 million. Average
price increases as a percentage of revenue were approximately 5.7%.

         Cost of Operations. Cost of operations in 1995 was $120.7 million
compared to $98.1 million in 1994, an increase of 23.1%. This increase in costs
was attributable primarily to increase in revenues described above. As a
percentage of revenues, cost of operations decreased to 55.5% in 1995 from 61.9%
in 1994. The resulting increase in margins was due primarily to better
internalization of waste flows in 1995 as compared to 1994 during which
Allied-collected waste disposed at Allied-owned and/or operated landfills, as
measured using disposal costs, was 34.8% of revenue compared to 62.0% for 1995.
Gross profit also increased because of increased operating efficiencies
resulting from improvements made to vehicles and equipment through capital
expenditures made in 1994 and 1995.

         Selling, General and Administrative Expenses. SG&A expenses increased
to $36.7 million in 1995 compared to $32.6 million in 1994, an increase of
12.7%. As a percentage of revenues, SG&A decreased to 16.9% in 1995 from 20.6%
in 1994. The increase in SG&A expenses resulted from expenses associated with
acquired companies and expenses incurred in connection with Allied's increase in
personnel and other expenses related to the anticipated growth of Allied as it
continues to acquire companies. The decrease in SG&A as a percentage of revenues
can be attributed to a significant increase in revenue producing assets while
corporate level personnel and other related expenses increased only moderately.

         Depreciation and Amortization Expense. Depreciation and amortization
expense in 1995 was $25.8 million compared to $16.9 million in 1994, an increase
of 52.3%. The increase in depreciation and amortization expense is due to
acquisitions and capital expenditures. Fixed assets increased to $366.6 million
at December 31, 1995 from $261.4 million at December 31, 1994 and goodwill
increased to $98.1 million at December 31, 1995 from $84.1 million at December
31, 1994. As a percentage of revenues, depreciation and amortization increased
to 11.9% in 1995 from 10.7% in 1994. This increase in primarily because
amortization of landfill airspace as a percentage of revenue increased to 2.7%
in 1995 from 1.0% in 1994 resulting from an increase in the rate of waste
internalization.

         Acquisition Related Costs. Costs of $1.5 million were incurred in
September 1995 for transaction and integration costs related to acquisitions
accounted for using the pooling-of-interests method for business combinations.
During 1994, no acquisitions were accounted for using this method.

         Unusual Items. In December 1994 the Company recorded a provision of
$2.1 million, in excess of the closure and post-closure reserves recorded in the
normal course of business, to recognize the estimated costs of additional
closure, post-closure and remedial measures related to its Norfolk landfill.

         Net Interest Expense. Net interest expense increased to $10.6 million
in 1995 compared to $12.4 million in 1994, a decrease of 13.8%. Interest charges
decreased in 1995 compared to 1994 because of an increase in the amount of
capitalized interest to $11.1 million in the 1995 period compared to $3.5
million in 1994. The amount of interest capitalized increased in 1995 because of
an increase in transfer stations and landfill airspace under development or
under application for development compared to 1994 and the acquisition of
additional landfills subsequent to 1994. The decrease in interest charges was
offset by an increase in the interest rate on the 1994 Notes, from 10.75% in
1994 to 12% in January 1995 and an increase in interest bearing debt to
approximately $223.9 million at December 31, 1995 from approximately $188.0
million at December 31, 1994, due primarily to acquisitions and capital
expenditures.


                                       21

<PAGE>   22
         Conversion Fees. A non-cash conversion fee of $2.2 million was incurred
in the fourth quarter of 1995 as a result of an inducement offered by Allied to
holders of certain convertible securities to exercise their conversion option to
receive Common Stock. The inducement fee consisted of payment of dividends or
interest from the conversion date through the first call or redemption date of
each convertible security. Approximately 7.8 million shares of Common Stock were
issued for conversion and approximately 285,000 were issued for the conversion
fee.

         Income Taxes. Income taxes reflect a 44.1% effective income tax rate in
1995 compared to a 18.6% effective rate in 1994. Allied's effective tax rate in
1995 and 1994 deviates from the federal statutory rates of 35% and 34%,
respectively, due to the effects of differences in the treatment of goodwill for
book and tax purposes, state income taxes, and other permanent differences.

         Extraordinary Items. In connection with the Securities Purchase
Agreement between the Company and TPG Partners, L.P. ("TPG") dated October 27,
1994, as amended (the "TPG Agreement"), the Company solicited and obtained
consents from a majority of the holders of the 1994 Notes causing modifications
to the indenture agreement and the execution of a supplemental indenture (the
"Supplemental Indenture"). Among other things, the Supplemental Indenture
increased the Company's restricted borrowing capacity (with certain limitations)
under current and future revolving credit agreements and lease lines from a
total of $35 million to $120 million, deleted certain borrowing restrictions,
changed certain financial ratio covenants and increased the per annum rate of
interest from 10.75% to 12.0%. The execution of the Supplemental Indenture,
which was effective January 1995, was accounted for as an early extinguishment
of debt. Accordingly, capitalized deferred debt issuance costs related to the
original indenture were written off as of December 31, 1994 and an extraordinary
charge of $4.6 million ($2.8 million net of income tax benefit) was recorded.
Additionally, in the first quarter of 1994, an extraordinary charge of $334,000
($206,000 net of income tax benefit) was recognized as result of the early
extinguishment of various debt instruments using the proceeds from the 1994
Notes.


LIQUIDITY AND CAPITAL RESOURCES

         Historically, the Company has satisfied its acquisition, capital
expenditure and working capital needs primarily through bank financing, public
offerings and private placements of debt and equity securities. Between January
1, 1994 and December 31, 1996, the Company completed the $1.275 billion Senior
Credit Facility (of which $517 million was repaid with proceeds from the
Canadian Sale in March 1997), a $525 million private placement of the 1996
Notes, a $100 million public offering of the 1994 Notes (substantially all of
which were repurchased pursuant to the Tender Offer in July 1996), a $50 million
private placement of Common Stock, a $300 million senior revolving credit
facility (all debt under which was repaid in December 1996), and a $48 million
public equity offering. Because of the capital intensive nature of the solid
waste industry, the Company has used, and expects to continue using amounts in
excess of the cash generated from operations to fund acquisitions and capital
expenditures, including landfill development. In connection with acquisitions,
the Company has assumed or incurred indebtedness with relatively short-term
repayment schedules, thereby increasing its current and medium-term liabilities.
Additionally, operating equipment has been acquired using financing leases which
have short and medium-term maturities. As a result, the Company has periodically
had low levels of working capital or working capital deficits.

(1)      Consists principally of provisions for depreciation and amortization,
         landfill closure and post-closure costs, doubtful accounts, potentially
         unrealizable acquisition costs and deferred income taxes.

         As of December 31, 1996, the Company had cash and cash equivalents of
$50.1 million. The Company's capital expenditure and working capital
requirements have increased significantly, reflecting the Company's rapid growth
by acquisition and development of revenue producing assets, and will increase
further as the Company continues to pursue its business strategy. During 1996
the Company completed the Laidlaw Acquisition for total consideration of
approximately $1.5 billion consisting of $1.2 billion cash, 14.6 million shares
of Common Stock, warrants to acquire 20.4 million shares of Common Stock, and
two junior subordinated debentures with an aggregate face amount of $318 million
and acquired 21 additional businesses for total consideration of approximately
$126.5 million of which approximately $73.9 million of such consideration was
paid in common stock and $3.6 million was paid in seller notes. Total annualized
revenues of the latter businesses are approximately $78.8 million. Subsequent to
December 31, 1996 the Company purchased 2 operating solid waste landfills with
estimated annual revenues of $26.8 million for an aggregate purchase price of
approximately $58.9 million of which approximately $6.5 million of such
consideration was paid in common stock. For the calendar year 1997, the Company
expects to spend approximately $126 million for capital, closure and
post-closure, and remediation expenditures relating to its landfill operations.
As the Company continues to acquire waste operations in 1997, additional capital
amounts will be required during 1997 for the acquisition of businesses and the
capital expenditure requirements related to those acquired businesses.


                                       23

         On December 31, 1996, the Company's debt structure consisted of $525
million of the 1996 Notes, amounts outstanding under the Senior Credit Facility
of approximately $975 million, and $110.7 million of Allied Canada Debentures.
In connection with the Canadian Sale, Allied repaid approximately $517 million
of the Senior Credit Facility. After giving effect to the Canadian Sale, there
is aggregate availability under the Senior Credit Facility of $300 million
pursuant to a revolving credit facility to be used for working capital, letters
of credit, acquisitions and other general corporate purposes. No more than $200
million of funded loans (excluding amounts outstanding pursuant to drawn letters
of credit) may be outstanding at one time, of which not more than $100 million
may be used for acquisitions. The indenture relating to the 1996 Notes and the
Senior Credit Facility contain financial and operating covenants and significant
restrictions on the ability of the Company to complete acquisitions, pay
dividends, incur indebtedness, make investments and take certain other corporate
actions. A substantial portion of the Company's available cash will be required
to be applied to service indebtedness, including indebtedness incurred to
finance the Laidlaw Acquisition, which is expected to include approximately $0.7
million for preferred stock dividends and approximately $126 million in annual
principal and interest payments (after giving effect to the payment of $517
million on the Senior Credit Facility after the Canadian Sale).

         The Company is also required to provide financial assurances to
governmental agencies under applicable environmental regulations relating to its
landfill operations. These financial assurances include performance bonds,
letters-of-credit and trust deposits required principally to secure the
Company's landfill estimated closure and post-closure obligations and collection
contracts. At December 31, 1996, the Company had outstanding approximately $47.0
million of performance bonds, $99.5 million in letters-of-credit and $2.6
million of trust deposits. During calendar year 1997, the Company expects to be
required to provide approximately $227.6 million in financial assurance
obligations relating to its landfill operations. The Company expects that
financial assurance obligations will increase in the future as it acquires and
expands its activities and that a greater percentage of the financial assurances
will be comprised of letters-of-credit.

         The Company has lease facilities (the "Lease Facilities") that allow it
to enter into equipment leases at rates ranging from similar term treasury note
rates plus 2.5% to 3.5% for terms of 36 to 84 months. In addition to equipment
leases outstanding at December 31, 1995 and 1996 of $32.7 million and $45.2
million, respectively, the Company had available lease commitments of $8.5
million and $11.9 million, respectively. The Company intends to enter into
master equipment lease facilities relating to the financing of the acquisition
of trucks and containers.

         The Company expects that Subtitle D and other regulations that apply to
the non-hazardous waste disposal industry will require the Company, as well as
others in the industry, to alter operations and to modify or replace existing
facilities. Such expenditures have been and will continue to be substantial.
Further regulatory changes could accelerate expenditures for closure and
post-closure monitoring and obligate the Company to spend sums in addition to
those presently reserved for such purposes. These factors, together with the
other factors discussed above, could substantially increase the Company's
operating costs and impair the Company's ability to invest in its facilities.

         The Company's ability to meet future capital expenditure and working
capital requirements, to make scheduled payments of principal of, to pay
interest on, or to refinance its indebtedness, and to fund capital amounts
required for the acquisition of businesses and the expansion of existing
businesses depends on its future performance, which, to a certain extent, is
subject to general economic, financial, competitive, legislative, regulatory and
other factors beyond its control. One of the primary factors impacting the
Company's future performance will be its ability to integrate the assets
acquired in the Laidlaw Acquisition after the Canadian Sale, and to reduce
redundancies and excess costs. These operations are significantly larger than
the Company's previous operations and represent a substantial increase in the
scope of the Company's business. Based upon the current level of operations and
anticipated growth, management of the Company believes that available cash flow,
together with available borrowing under the Senior Credit Facility, the Lease
Facilities and other sources of liquidity, will be adequate to meet the
Company's anticipated future requirements for working capital,
letters-of-credit, capital expenditures, scheduled payments of principal of and
interest on debt incurred under the Senior Credit Facility, interest on the 1996
Notes and capital amounts required for acquisitions and expansion. However, the
principal payments at maturity on the 1996 Notes may require refinancing. There
can be no assurance that the Company's 


                                       24

<PAGE>   25
business will generate sufficient cash flow from operations or that future
financings will be available in an amount sufficient to enable the Company to
service its indebtedness or to make necessary capital expenditures, or that any
refinancing would be available on commercially reasonable terms if at all.
Additionally, depending on the timing, amount and structure of any future
acquisitions and the availability of funds under the acquisition facility under
the Senior Credit Facility, the Company may need to raise additional capital to
fund the acquisition and integration of additional solid waste businesses. The
Company may raise such funds through additional bank financings or public or
private offerings of its debt and equity securities. There can be no assurance
that the Company will be able to secure such funding, if necessary, on favorable
terms, if at all. If the Company is not successful in securing such funding, the
Company's ability to pursue its business strategy may be impaired and results of
operations for future periods may be negatively affected.


SIGNIFICANT FINANCING EVENTS

         In connection with the Laidlaw Acquisition, the Company and Allied
Waste North America, Inc., a wholly owned subsidiary of the Company ("Allied
NA") executed a $1.275 billion Credit Agreement (the "Credit Agreement") among
Goldman Sachs Credit Partners L.P., Credit Suisse and Citibank, N.A.
(collectively the "Agents") (the "Senior Credit Facility"). The Senior Credit
Facility was comprised of (i) a $300 million revolving credit facility; (ii) a
$475 million 5.5 year senior term loan; (iii) a $100 million 6.5 year
Amortization Extended Term Loan AXEL(TM)A; (iv) a $200 million 7.5 year
AXEL(TM)B; and (v) a $200 million 8.5 year AXEL(TM)C. Of the $300 million
available under the revolving credit facility, no more than $200 million may be
outstanding at one time, of which no more than $100 million may be used to
finance permitted acquisitions ("Acquisition Loans"), as defined in the Credit
Agreement, and no more than $150 million may be used for the issuance of standby
letters-of- credit. Borrowings under the revolving credit facility may be used
for permitted acquisitions, repay existing indebtedness or indebtedness assumed
through acquisition and for general corporate purposes. Acquisition Loans
outstanding as of September 2000 become payable quarterly, with a final maturity
of June 2002 and may not be re-borrowed after September 2000. Loans, other than
Acquisition Loans, outstanding under the revolving credit facility are payable
in June 2002. Borrowings under the senior term loan and the AXELs were use to
pay a portion of the cash purchase price of the Laidlaw Acquisition. Amounts
outstanding under the senior term loan and AXELs are payable quarterly,
beginning in June 1997, with final maturities ranging from June 2002 to June
2005. The Credit Agreement contains a number of covenants that, among other
things, require Allied NA to maintain certain financial ratios which commence
with the quarter ended March 31, 1997, and limit Allied NA's ability to make
acquisitions, purchase fixed assets above certain amounts, incur additional
indebtedness and liens, pay dividends except on certain preferred stock, make
optional prepayments on certain subordinated indebtedness, including the 1996
Notes, enter into certain transactions with affiliates or enter into a merger,
consolidation or sale of substantially all of Allied NA's assets. The Senior
Credit Facility is secured by a pledge of the stock of substantially all of
Allied NA's subsidiaries, liens on substantially all personal property and a
negative pledge of assets of Allied NA and its subsidiaries. In addition to the
security granted, the Agents reserve the right to file mortgages on all real
property of Allied NA and its subsidiaries at their sole discretion. The Senior
Credit Facility is guaranteed by the Company and all the subsidiaries of Allied
NA. Allied NA intends on using proceeds from the revolving credit facility to
make strategic acquisitions, repay indebtedness assumed through acquisitions,
and for general corporate purposes. As of December 31, 1996, Allied NA had no
funded loans outstanding and had issued approximately $46 million of standby
letters-of-credit, leaving $200 million available for funded loans and $104
million available for letters-of-credit. In connection with the Canadian Sale,
Allied paid approximately $517 million of the Senior Credit Facility. Payments
were made on a pro rata basis between the term loan and each of the AXEL
traunches as provided by the Credit Agreement. 


                                       25

<PAGE>   26
         Also in connection with the Laidlaw Acquisition, Allied NA issued $525
million of 10.25% Senior Subordinated Notes due 2006 in a Rule 144A private
offering. Net proceeds from the sale of the 1996 Notes, after the underwriting
discount and other expenses, were approximately $509 million. The net proceeds
were used to pay a portion of the cash purchase price of the Laidlaw
Acquisition, repay amounts outstanding under the Company's previous $300 million
credit facility with Credit Suisse as agent, fund certain acquisitions and for
general corporate purposes. Allied NA has an obligation to offer fully
registered securities, pursuant to an exchange offer, that are substantially
identical to the 1996 Notes. If Allied NA fails to effect an exchange offer, or
if the registration statement relating to the exchange offer shall be withdrawn
by Allied NA before certain dates, Allied NA will be subject to penalty interest
in varying amounts ranging from 0.25% to 1.0% per annum on the principal amount
thereof as liquidated damages to the holders of the 1996 Notes. On February 28,
1997, Allied NA filed a registration statement relating to the exchange offer
with the Securities and Exchange Commission on Form S-4. The 1996 Notes cannot
be redeemed until December 1, 2001, except under certain circumstances. Prior to
December 1, 2001, the 1996 Notes are subject to redemption, at the option of
Allied NA, at the greater of (i) 100% of the principal amount of (ii) the sum of
the present values of the remaining scheduled payments of principal and interest
thereon discounted to maturity on a semiannual basis at a comparable treasury
yield plus 75 basis points, plus in each case accrued and unpaid interest to the
date of redemption. At any time prior to December 1, 1999, up to 33% of
principal amount of 1996 Notes will be redeemable, at the option of Allied NA,
from the proceeds of one or more public offerings of capital stock by the
Company at a redemption price of 110.25% of principal amount, plus accrued
interest. The 1996 Notes are guaranteed by the Company and substantially all of
Allied NA's subsidiaries, the guarantees of which are expressly subordinated to
the guarantees of Allied NA's Senior Credit Facility. The 1996 Notes contain
several covenants, the most restrictive of which limits Allied NA and its
subsidiaries' ability to incur additional indebtedness without complying with an
interest coverage ratio test. Other covenants contain limitations on payment of
dividends except for certain preferred stock, issuance of redeemable preferred
stock, transactions with affiliates, granting of liens and security interests,
sales of assets and the use of proceeds from sales of assets, mergers and
consolidations, and changes of control. The covenants do permit Allied NA to
incur certain indebtedness including the Senior Credit Facility, indebtedness
issued and/or assumed in permitted acquisitions and other indebtedness which is
limited to a certain percentage of Allied NA's total assets.

         In connection with the Laidlaw Acquisition, Allied Waste Finance
(Canada) Ltd. ("Allied Finance") issued to Laidlaw: (i) the Allied Finance 7%
Debenture (the "Allied Finance 7% Debenture") and (ii) the Allied Finance Zero
Coupon Debenture (the "Allied Finance Zero Coupon Debenture", and together with
the Allied Finance 7% Debenture the "Allied Finance Debentures"). The principal
of the Allied Finance Debentures is payable in December 2008, subject to earlier
prepayment as described below. The Allied Finance 7% Debenture will bear
interest at the fixed rate of 7% per annum payable semi-annually, except for the
first three years during which the interest payments will be deferred. Laidlaw
and the Company have entered into a subscription agreement under which, at the
option of the Company, Laidlaw must subscribe to common stock of the Company in
equal dollar amounts of the interest and principal payments due on the Allied
Finance 7% Debenture. Before its maturity, the Allied Finance Zero Coupon
Debenture will not bear interest. For the first five years after issuance, the
Allied Finance 7% Debenture may not be prepaid by Allied Finance, subject to
change of control provisions described below. Following the fifth anniversary
and until maturity, Allied Finance will have the option to prepay the Allied
Finance 7% Debenture, in whole or in part, at a scheduled discount from the face
amount of the Allied Finance 7% Debenture. The Allied Finance Zero Coupon
Debenture is not pre-payable at the option of Allied Finance prior to it stated
maturity, subject to the change of control provision. Upon a change of control
(as defined in the Allied Finance Debentures), Allied Finance will be obligated
to offer to prepay the Allied Finance Debentures at a predetermined discount to
the face amount of each debenture, respectively. Subject to certain
subordination provisions contained in the Allied Finance Debentures, the
maturity of the Allied Finance Debentures may be accelerated if a default (as
defined in the Allied Finance Debentures) occurs. The Allied Finance Debentures
are unsecured obligations and do not contain any restrictive or financial
covenants. The Allied Finance Debentures are guaranteed by the Company on a
subordinated basis to the Senior Credit Facility and the 1996 Notes.

<PAGE>   27
         In connection with Laidlaw Acquisition, the Company issued a warrant to
Laidlaw for the purchase of 20.4 million shares of common stock of the Company
at an exercise price of $8.25 per share (the "Warrant"). The Warrant expires in
December 2008. Laidlaw or any Laidlaw subsidiary may exercise the Warrant only
after the occurrence of a change of control of the Company. Laidlaw is permitted
to transfer the Warrant to any subsidiary of Laidlaw, but not to any other
affiliate of Laidlaw unless the transferee receives the Warrant pursuant to a
pro rata distribution of Warrants to all stockholders of all classes of
Laidlaw's outstanding capital stock. Laidlaw is permitted to transfer the
Warrant to anyone other than one of its affiliates, but only if, after the
transfer, the transferee and its affiliates beneficially own 9% or less of the
total number of shares of common stock of the Company then outstanding.

         In January 1994, the Company issued $100 million of 10 3/4% senior
subordinated notes (the "1994 Notes"). The net proceeds from the sale of the
1994 Notes after underwriting discount and other expenses, were approximately
$95 million. In July 1996, the Company completed the Tender Offer and purchased
substantially all of its 1994 Notes at the redemption price of $1,157.50 per
$1,000 principal amount. In connection with the Tender Offer, the Company
recognized an extraordinary charge of $18.4 million ($11.0 million net of income
tax benefit), in the third quarter of 1996. The Company also received a consent
from a majority of the holders of the 1994 Notes to eliminate all substantive
financial covenants associated with the remaining 1994 Notes.

         Simultaneously with the Tender Offer in July 1996, the Company
completed a new $300 million revolving credit facility which was extinguished on
December 30, 1996 in connection with the financing of the Laidlaw Acquisition.
The Company recognized an extraordinary charge of $4.0 million ($2.4 million net
of income tax benefit), in the fourth quarter.

         On January 24, 1996, the Company completed a public offering of its
Common Stock. It issued 7.6 million shares for approximately $48 million net of
$5.2 million in underwriter discounts, commissions and offering costs. The net
proceeds from the offering were used to repay amounts outstanding under the
Company's outstanding credit agreement and for other general corporate purposes.

         During 1995, the Company offered to holders of all of its Series D, 9%
and $90 convertible preferred stock and its 6% Convertible Subordinated notes an
inducement to exercise their conversion option to receive Allied Common Stock.
The inducement consisted of the payment of dividends and interest that the
holders of these securities would have received from the date of conversion
through the first call or redemption date of each security. In total, 7,757,056
shares of Common Stock were issued upon conversion. Substantially all of the
Series D preferred stock and 6% Convertible Subordinated notes were converted,
all but 5,029 shares of the 9% preferred stock was converted and all of the $90
preferred stock was converted. Accordingly, the Company's annual dividend and
interest requirements decreased by approximately $2.7 million and $0.8 million,
respectively. The inducement resulted in a 1995 conversion fee charge of
approximately $2.2 million paid in 285,000 shares of Common Stock.

         On January 30, 1995, the Company obtained stockholder approval of the
issuance of 11,709,602 shares of Common Stock to TPG and an affiliate, for $50
million (less approximately $5.0 million of direct offering costs and other
costs related to an amendment to the 1994 Notes).

DISCLOSURE REGARDING FORWARD LOOKING STATEMENTS

         This "Management's Discussion and Analysis of Financial Condition and
Results of Operations" includes forward looking statements within the meaning of
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended ("Forward Looking Statements"). All
statements other than statements of historical fact included in this section,
are Forward Looking Statements. Although the Company believes that the
expectations reflected in such Forward Looking Statements are reasonable, it can
give no assurance that such expectations will prove to have been correct.
Generally, these statements relate to business plans or strategies, projected or
anticipated benefits or other consequences of such plans or strategies, number
of acquisitions and projected or anticipated benefits from acquisitions made by
or to be made by the Company, or projections involving anticipated revenues,
earnings, levels of capital expenditures or other aspects of operating results.
All phases of the Company operations are subject to a number of uncertainties,
risks and other influences, many of which are outside the control of the Company
and any one of which, or a combination of which, could materially affect the
results of the Company's operations and whether Forward Looking Statements made
by the Company ultimately prove to be accurate. Such important factors
("Important Factors") that could cause actual results to differ materially from
the Company's expectations are disclosed in this section and elsewhere in this
report. All subsequent written and oral Forward Looking Statements attributable
to the Company or persons acting on its behalf are expressly qualified in their
entirety by the Important Factors described below that could cause actual
results to differ from the Company's expectations.

         Competition. The solid waste collection and disposal business is highly
competitive. The Company competes with numerous waste management companies, a
number of which have significantly larger operations and greater resources than
the Company. The Company also competes with those counties and municipalities
that maintain their own waste collection and disposal operations. Forward
Looking Statements assume that the Company will be able to effectively compete
with the other waste management companies and municipalities.

         Acquisition and Internal Development Targets. The Company's ongoing
acquisition program is a key element of its expansion strategy. In addition,
obtaining landfill and transfer station permits has become increasingly
difficult, time consuming and expensive. There can be no assurance, however,
that the Company will succeed in obtaining such permits, or in locating
appropriate solid waste businesses at price levels that the Company considers
appropriate and that reflect historical prices. The Forward Looking Statements
assume the Company will be successful in obtaining permits and that a number of
acquisition candidates and landfill properties sufficient to meet the Company's
goals will be available for purchase and that the Company will be able to
complete the acquisition at prices that the Company has experienced in the past
two years.

         Integration. The Company's financial position and results of operations
depend to a large extent on the integration of recently acquired businesses. The
Forward Looking Statements assume that integration of acquired companies,
including the internalization of waste, will require from zero to nine months
from the date the acquisition closes. Failure to achieve effective integration
in the anticipated time period or at all could have an adverse effect on the
Company's future results of operations.

         Ongoing Capital Requirements. To the extent that internally generated
cash and cash available under the Company's existing credit facilities are not
sufficient to provide the cash required for future operations, capital
expenditures, acquisitions, debt repayment obligations and/or financial
assurance obligations, the Company will require additional equity and/or debt
financing in order to provide such cash. The Company has incurred significant
debt obligations in the last two years, which entail substantial debt service
costs. The Forward Looking Statements assume that the Company will be able to
raise the capital necessary to finance such requirements at interest rates that
are as good as or better than those it is currently experiencing. There can be
no assurance, however, that such financing will be available or, if available,
will be available on terms satisfactory to the Company.


                                       28

<PAGE>   29
         Economic Conditions. The Company's business is affected by general
economic conditions. The Forward Looking Statements assume that the Company will
be able to achieve certain volume and price growth estimates which are not
impacted by an economic downturn or other factors outside of its control. (As
revenue of the Company continues to grow it is likely that the rates of internal
growth will reflect growth rates which are less than those experienced in 1995
and 1996.) There can be no assurance that an economic downturn or other factors
outside of its control will not result in a reduction in the estimated rates of
growth or a decrease in the volume of waste being collected or disposed of by
the Company and/or in the price that the Company charges for its services.

         Weather Conditions. Protracted periods of inclement weather may
adversely affect the Company's operations by interfering with collection and
landfill operations, delaying the development of landfill capacity and/or
reducing the volume of waste generated by the Company's customers. In addition,
particularly harsh weather conditions may result in the temporary suspension of
certain of the Company's operations. The Forward Looking Statements do not
assume that such weather conditions will occur which might require the Company
to dispose of waste at alternate facilities and at higher costs.

         Dependence on Senior Management. The Company is highly dependent upon
its senior management team. In addition, as the Company continues to grow, its
requirements for operations management with waste industry experience will also
increase. The availability of such experienced management is not known. The
Forward Looking Statements assume that experienced management will be available
when needed by the Company at compensation levels that are within industry
norms. The loss of the services of any member of senior management or the
inability to hire experienced operations management could have a material
adverse effect on the Company.

         Influence of Government Regulation. The Company's operations are
subject to and substantially affected by extensive federal, state and local
laws, regulations, orders and permits, which govern environmental protection,
health and safety, zoning and other matters. These regulations may impose
restrictions on operations that could adversely affect the Company's results,
such as, but not limited to, restrictions on the expansion of disposal
facilities, restrictions on or the banning of disposal of out-of-state waste or
certain categories of waste or mandates regarding the disposal of solid waste.
Because of heightened public concern, companies in the waste management business
may become subject to judicial and administrative proceedings involving federal,
state or local agencies. These governmental agencies may seek to impose fines or
to revoke or deny renewal of operating permits or licenses for violations of
environmental laws or regulations or to require remediation of environmental
problems at sites or nearby properties, or resulting from transportation or
predecessors' transpiration and collection operations, all of which could have a
material adverse effect on the Company. Liability may also arise from actions
brought by individuals or community groups in connection with the permitting or
licensing of operations, any alleged violations of such permits and licenses or
other matters. The Forward Looking Statements assume that there will be no
materially negative impact on its operations due to government regulation.

         Potential Environmental Liability. The Company may incur liabilities
for the deterioration of the environment as a result of its operations. Any
substantial liability for environmental damage could materially adversely affect
the operating results and financial condition of the Company. Due to the limited
nature of the Company's insurance coverage of environmental liability, if the
Company were to incur a liability for environmental damage, its business
liquidity, financial position or results of operations could be materially
adversely affected. The Forward Looking Statements assume that the Company will
not incur any material environmental liabilities other than those for which a
provision has been recorded in the consolidated financial statements and
disclosed in the notes thereto.

<PAGE>   30
INFLATION AND PREVAILING ECONOMIC CONDITIONS

         To date, inflation has not had a significant impact on the Company's
operations. Consistent with industry practice, most of the Company's contracts
provide for a pass through of certain costs, including increases in landfill
tipping fees and, in some cases, fuel costs. The Company therefore, believes it
should be able to implement price increases sufficient to offset most cost
increases resulting from inflation. However, competitive factors may require the
Company to absorb cost increases, resulting from inflation. The Company is
unable to determine the future impact of a sustained economic slowdown.

SEASONALITY

         The Company believes that its collection and landfill operations can be
adversely affected by protracted periods of inclement weather which could delay
the development of landfill capacity or transfer of waste and/or reduce the
volume of waste generated.

To Allied Waste Industries, Inc.



We have audited the accompanying consolidated balance sheets of Allied Waste
Industries, Inc., (a Delaware corporation) and subsidiaries as of December 31,
1996 and 1995, and the related consolidated statements of operations,
stockholders' equity and cash flows for the three years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Allied Waste Industries, Inc.
and subsidiaries as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Allied Waste Industries, Inc. ("Allied" or the "Company") is
incorporated under the laws of the State of Delaware. Allied is a solid waste
management company providing non-hazardous waste collection, transfer, recycling
and disposal services in selected markets.

  Principles of consolidation and presentation --

         The consolidated financial statements include the accounts of Allied
and its subsidiaries. All significant intercompany accounts and transactions are
eliminated in consolidation. The consolidated financial statements and
accompanying notes have also been restated to reflect acquisitions accounted for
as poolings-of-interests (See Note 2).

         Certain reclassifications have been made in prior period financial
statements to conform to the current presentation.

  Cash and cash equivalents --

         Cash equivalents are investments with original maturities less than
ninety days. Such instruments are stated at quoted market prices.

  Concentration of credit risk --

         Financial instruments that potentially subject the Company to
concentrations of credit risk consist of cash and cash equivalents and trade
receivables. The Company places its cash and cash equivalents with high quality
financial institutions and limits the amount of credit exposure to any one
financial institution.

         The Company provides services to commercial and residential customers
in the United States. Concentrations of credit risk with respect to trade
receivables are limited due to the large number of customers comprising the
Company's customer base. The Company performs ongoing credit evaluations of its
customers, but does not require collateral to support customer receivables. The
Company establishes an allowance for doubtful accounts based on factors
surrounding the credit risk of specific customers, historical trends and other
information.

  Inventory --

         Inventory is stated at the lower of cost (first-in, first-out method)
or market and consists principally of equipment parts, materials and supplies.

  Property and equipment --

         Property and equipment are recorded at cost, which includes interest to
finance the acquisition and construction of major capital additions during the
development phase, primarily landfills and transfer stations. Interest
capitalized in the three years ended December 31, 1996 was $3,517,000,
$11,088,000 and $12,970,000, respectively. Depreciation is provided on the
straight-line method over the estimated useful lives of buildings (30-40 years),
vehicles and equipment (3-15 years), containers and compactors (5-10 years) and
furniture and office equipment (3-8 years). The cost of landfill airspace,
including original acquisition cost and incurred and projected landfill
preparation costs, is amortized based on tonnage as landfill airspace is
consumed. Other current assets include the current portion of landfill
amortization costs of $7,103,000 and $23,820,000 at December 31, 1995 and 1996,
respectively. Management periodically reviews the realizability of its
investment in operating landfills. Should events and circumstances indicate that
any of the Company's landfills be reviewed for possible impairment, such


                                       36

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

review for recoverability will be made in accordance with Emerging Issues Task
Force Discussion Issue ("EITF") 95-23. The EITF outlines how cash flows for
environmental exit costs should be determined and measured.

         Expenditures for major renewals and betterments are capitalized, while
expenditures for maintenance and repairs which do not improve assets or extend
their useful lives are charged to expense as incurred. For the three years ended
December 31, 1996, maintenance and repair expenses charged to cost of operations
were $12,917,000, $14,741,000 and $14,750,000, respectively. When property is
retired, the related cost and accumulated depreciation are removed from the
accounts and any resulting gain or loss is recognized.

  Goodwill --

         Goodwill is the cost in excess of fair value of identifiable assets of
acquired businesses and has been amortized on a straight-line basis over 40
years. The Company continually evaluates whether events and circumstances have
occurred subsequent to its acquisition, that indicate the remaining estimated
useful life of goodwill may warrant revision or that the remaining balance of
goodwill may not be recoverable. When factors indicate that goodwill should be
evaluated for possible impairment, the Company uses an estimate of the related
business segment's discounted future cash flows over the remaining life of the
goodwill in measuring whether the goodwill is recoverable. Goodwill amortization
of $2,203,000, $3,679,000 and $2,247,000 is included in depreciation and
amortization for the three years in the period ended December 31, 1996,
respectively. Accumulated goodwill amortization was $9,631,000 and $11,878,000
at December 31, 1995 and 1996, respectively.

  Other assets --

         Other assets includes notes receivable, landfill closure deposits,
deferred charges and miscellaneous non- current assets. Deferred charges include
costs incurred to acquire businesses and to obtain equity and debt financing.
Upon consummation of an acquisition, deferred costs relating to acquired
businesses accounted for as purchases are allocated to goodwill or landfill
airspace while costs relating to acquired businesses accounted for as
poolings-of-interests are expensed. Direct costs related to acquisitions under
evaluation are capitalized and reviewed for realization on a periodic basis.
These costs are expensed when management determines that the capitalized costs
provide no future benefit. Upon funding of equity and debt offerings, deferred
costs are charged to additional paid-in capital or are capitalized as debt
issuance costs and amortized using the interest method over the life of the
related debt. Miscellaneous assets include consulting and non-competition
agreements which are being amortized in accordance with the terms of the
respective agreements and contracts.

  Accrued closure and post-closure costs --

         Accrued closure and post-closure costs represent an estimate of the
current value of the future obligation associated with closure and post-closure
monitoring of non-hazardous solid waste landfills currently owned and/or
operated by the Company. Site specific closure and post-closure engineering cost
estimates are prepared annually for landfills owned and/or operated by the
Company for which it is responsible for closure and post-closure. The present
value of estimated future costs are accrued based on accepted tonnage as
landfill airspace is consumed. Discounting of future costs is applied where the
Company believes that both the amounts and timing of related payments are
reliably determinable. The Company periodically updates its estimates of future
closure and post-closure costs. The impact of changes which are determined to be
changes in estimates are accounted for on a prospective basis.

                          ALLIED WASTE INDUSTRIES, INC.
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

  Environmental costs --

         Allied accrues for losses associated with environmental remediation
obligations when such losses are probable and reasonably estimable. Accruals for
estimated losses from environmental remediation obligations generally are
recognized no later than completion of the remedial feasibility study. Such
accruals are adjusted as further information develops or circumstances change.
Costs of future expenditures for environmental remediation obligations are not
discounted to their present value. Recoveries of environmental remediation costs
from other parties are recorded as assets when their receipts are deemed
probable.

  Deferred royalties and other long-term obligations --

         Other long-term obligations include non-competition agreements with
former owners of acquired companies and deferred royalty obligations. Guaranteed
minimum royalty obligations are recorded upon acquisition of the related asset
whereas royalty obligations dependent upon future waste accepted at landfills
are expensed as earned.

  Revenue --

         Advance billings are recorded as unearned income, and revenue is
recognized as income when services are provided.

  Acquisition related costs --

         In connection with the Laidlaw Acquisition, the Company incurred
approximately $84.6 million in charges primarily associated with the
acquisition, which include approximately $51.5 million of environmental related
matters, $18.4 million of asset impairments and abandonments, and $14.7 million
of acquisition liabilities, of which $2.0 million relates to litigation matters,
$5.4 million relates to relocation and transition costs and bonuses, $3.8
million relates to taxes, claims and assessments and other integration costs,
and $3.5 million relates to acquired accounts receivable considered
uncollectible.

         In connection with the Laidlaw Acquisition, Allied engaged an
independent environmental consulting firm to assist in conducting an
environmental assessment of the real property owned by the acquired subsidiaries
or third-parties, and properties under the management of the acquired companies.
Several contaminated landfills and other properties have been identified, two of
which are owned by subsidiaries of the Company, that would require those
subsidiaries to incur costs for incremental closure and post-closure measures,
remediation activities and litigation costs. The costs of performing the
investigation, design, remediation and the allocation of responsibility to the
subsidiaries of Allied vary significantly between sites. Based on information
available to the Company, Allied recorded a provision of $51.5 million for
environmental matters, including closure and post-closure costs, in the 1996
statement of operations and expects these amounts to be disbursed over the next
30 years.

         As a result of the Laidlaw Acquisition, Allied increased its revenue
base by approximately 400% and entered into 14 new markets where it believes
that it can execute its operating strategy. In connection with the significant
increase in size and the redirection of its strategic operating emphasis, Allied
determined that certain asset values have become impaired as they will provide
no further benefit to Company. Included among the asset impairments are costs of
$10.8 million related to over 50 noncompetition agreements in several markets
where the counter party no longer poses a significant threat due to Allied's
increased size, costs of $4.8 million for discontinued facilities and costs of
$2.8 million for market development activities no longer being pursued.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         Costs of $7.1 million were incurred in 1996 compared to $1.5 million in
1995 for transaction and integration costs directly related to acquisitions
accounted for using the pooling-of-interests method for business combinations

  Unusual items --

         In December 1996 the Company recorded $5.7 million in unusual charges
including $2.0 million in connection with the ongoing investigation and
remediation of the Company's Norfolk landfill and $3.7 million of other
non-recurring valuation adjustments.

  Extraordinary loss --

         On July 31, 1996, the Company completed a tender offer (the "Tender
Offer") and purchased, substantially all of its $100 million 12% Senior
Subordinated Notes due 2004 (the "1994 Notes") at the redemption price of
$1,157.50 per $1,000 note. An extraordinary charge to earnings related to the
Tender Offer of approximately $18.4 million ($11.0 million net of income tax
benefit) was charged to earnings in the third quarter of 1996. The Company also
received a consent from a majority of the holders of the 1994 Notes to eliminate
all substantive financial covenants associated with the remaining 1994 Notes.

         In addition, in December of 1996, the Company refinanced its $300
million senior revolving credit facility with the proceeds from the Senior
Credit Facility related to the Laidlaw Acquisition and recognized an
extraordinary charge of approximately $4.0 million ($2.4 million net of income
tax benefit).

         In connection with the Securities Purchase Agreement between the
Company and TPG dated October 27, 1994, as amended, the Company solicited and
obtained consents from a majority of the holders of its 10.75% 1994 Notes
causing modifications to the indenture agreement and the execution of a
supplemental indenture (the "Supplemental Indenture"). Among other things the
Supplemental Indenture increased the Company's restricted borrowing capacity
(with certain limitations) under current and future revolving credit agreements
and lease lines from a total of $35 million to $120 million, deleted certain
borrowing restrictions, changed certain financial ratio covenants and increased
the per annum rate of interest from 10.75% to 12.0%. The execution of the
Supplemental Indenture, which was effective January 30, 1995, was accounted for
as an early extinguishment of debt. Accordingly, capitalized deferred debt
issuance costs related to the original indenture were written off as of December
31, 1994 and an extraordinary charge of $4,595,000, ($2,823,000 net of income
tax benefit), was recorded. Additionally, in the first quarter of 1994, an
extraordinary charge of $334,000, ($206,000 net of income tax benefit) was
recognized as a result of the early extinguishment of various debt instruments
using the proceeds from the $100 million 1994 Notes.

  Use of estimates --

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities,
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Final settlement amounts could differ from those estimates.

         The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of Statement of
Financial Accounting Standards ("SFAS") No. 107, "Disclosures About Fair Value
of Financial Instruments". The Company's Financial Instruments as defined by
SFAS No. 107 include cash, money market funds, accounts receivable, accounts
payable, long-term debt and convertible subordinated debt. The estimated fair
value amounts have been determined by the Company at December 31, 1996 using
available market information and valuation methodologies described below.
Considerable judgment is required in interpreting market data to develop the
estimates of fair value. Accordingly, the estimates may not be indicative of the
amounts that could be realized in a current market exchange. The use of
different market assumptions or valuation methodologies could have a material
effect on the estimated fair value amounts.

         The carrying value of cash, money market funds, accounts receivable and
accounts payable approximate fair values due to the short-term maturities of
these instruments.

         The Company's 1996 Notes (see Note 5) had a fair value of $548.6
million at December 31, 1996 based upon quoted market prices. The convertible
subordinated debt has a fair value of approximately $2.4 million based upon the
conversion features of the related instruments and market price of the Company's
common stock at December 31, 1996. The fair value of the Zero Coupon Debenture
and 7% Debenture (see Note 5) approximates book value at December 31, 1996 due
to the short passage of time since their origination. Management believes the
carrying value of all remaining long-term debt approximates fair value.

 Stock-based compensation plans --

         The Company accounts for its stock-based compensation plans under
Accounting Principles Board Opinion No. 25, ("APB No. 25"). Effective in January
1, 1996, the Company adopted the disclosure option of SFAS No. 123, "Accounting
for Stock-based Compensation." SFAS No. 123 requires that companies which do not
elect to account for stock-based compensation as prescribed by the statement,
shall disclose the pro forma effects on earnings and earnings per share as if
SFAS No. 123 had been adopted. Additionally, certain other disclosures with
respect to stock compensation and the related assumptions are used to determine
the pro forma effects of SFAS No. 123.

 Accounting pronouncements not yet required to be adopted --

         In March 1997 the Financial Accounting Standards Board (FASB) issued
FASB Statement No. 128 "Earnings Per Share". The new statement is effective for
fiscal years ending after December 15, 1997 and will require restatement of
prior years' earnings per share. The Company has not quantified the effect of
applying the new statement.

2. BUSINESS COMBINATIONS

         Acquisitions accounted for as purchases are reflected in the results of
operations since the date of purchase in Allied's consolidated financial
statements. The results of operations for acquisitions accounted for as
poolings-of-interests are included in Allied's consolidated financial statements
for all periods presented. Often the final determination of the cost, and the
allocation thereof, of certain of the Company's acquisitions is subject to
resolution of certain contingencies. Once such contingencies are achieved, the
purchase price is adjusted. Shares issued in connection with business
acquisitions have been valued taking into consideration certain restrictions
placed on the stock.

         On December 30, 1996, the Company completed the acquisition of
substantially all of the non-hazardous solid waste management business conducted
by Laidlaw in the United States and Canada, for total consideration of
approximately $1.5 billion comprised of $1.2 billion cash, 14.6 million shares
of Common Stock, a warrant to acquire 20.4 million shares of Common Stock
(valued based on an appraisal by an independent investment banking firm), and a
zero percent and a 7% junior subordinated debenture. The cash consideration was
financed from the proceeds of the Senior Credit Facility and the sale of the
1996 Notes (see Note 5).

         On March 16, 1997, pursuant to a share purchase agreement with USA
Waste Services, Inc. ("USA Waste"), the Company sold to USA Waste (the "Canadian
Sale") all of the Canadian nonhazardous solid waste management operations of the
Company acquired from Laidlaw for approximately $518 million. The Company used
the proceeds from the Canadian Sale to pay down approximately $517 million in
debt under the Senior Credit Facility.

          In connection with the Laidlaw Acquisition, a subsidiary of the
Company issued a $150 million 7% Junior Subordinated Debenture (the "7%
Debenture") and a $168.3 million Zero Coupon Debenture (the "Zero Coupon
Debenture" and together with the 7% Debenture, the "Allied Debentures"). The 7%
Debenture bears interest at a fixed rate of 7% per annum payable semi-annually,
except for the first three years during which the interest payments are
deferred. The 7% Debenture and the Zero Coupon Debenture have an effective
interest rate of 14% and have been recorded at a net discounted amount of $77.5
million and $33.2 million, respectively, at December 31, 1996. The Allied
Debentures are due December 2008. Upon a change in control, the Company is
obligated to offer to prepay the Allied Debentures at a predetermined discount
to the face amount of each debenture. The Allied Debentures are guaranteed by
the Company and do not contain any restrictive or financial covenants.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         The $2.0 million notes payable to related parties were issued in April
1995 in accordance with an agreement to acquire certain real estate. This
agreement was executed by one of the Company's subsidiaries prior to the
Company's acquisition of the subsidiary. The agreement required the payment of
an aggregate of $5.6 million to the previous owners upon issuance of a permit to
operate a landfill. Subsequent to execution of this agreement, the previous
owners became stockholders of the Company. These notes bear interest at 12% per
annum with monthly principal and interest payments through maturity in May 1999
and are guaranteed by the Company.

         In connection with the Laidlaw Acquisition, the Company and Allied
Waste North America, Inc., a wholly owned subsidiary of the Company ("Allied
NA") executed a $1.275 billion Credit Agreement (the "Senior Credit Facility").
The Senior Credit Facility was comprised of (i) a $300 million revolving credit
facility; (ii) a $475 million 5.5 year senior term loan; (iii) a $100 million
6.5 year Amortization Extended Term Loan AXEL(TM)A; (iv) a $200 million 7.5 year
AXEL(TM)B; and (v) a $200 million 8.5 year AXEL(TM)C. Of the $300 million
available under the revolving credit facility, no more than $200 million may be
outstanding at one time, of which no more than $100 million may be used to
finance permitted acquisitions ("Acquisition Loans"), as defined in the Credit
Agreement, and no more than $150 million may be used for the issuance of standby
letters-of-credit. Amounts outstanding under the Senior Credit Facility are
payable quarterly, beginning in June 1997, with final maturities in June 2005.
The Senior Credit Facility is secured by a pledge of the stock of substantially
all of Allied NA's assets and is guaranteed by the Company and all the
subsidiaries of Allied NA. As of December 31, 1996, Allied NA had no funded
loans outstanding and had issued approximately $46 million of standby
letters-of-credit, leaving $200 million available for funded loans and $104
million available for letters-of-credit. In connection with the Canadian Sale,
Allied paid approximately $517 million of the Senior Credit Facility. Payments
were made on a pro rata basis between the term loan and each of the AXEL
traunches as provided by the Senior Credit Facility.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         In connection with the Laidlaw Acquisition, Allied NA issued $525
million of 10.25% Senior Subordinated Notes due 2006 (the "1996 Notes") in a
Rule 144A offering. Net proceeds from the sale of the 1996 Notes, after the
underwriting discount and other expenses, were approximately $509 million. The
net proceeds were used to pay a portion of the cash purchase price of the
Laidlaw Acquisition, repay amounts outstanding under the Company's previous $300
million credit facility, fund certain acquisitions and for general corporate
purposes. The 1996 Notes cannot be redeemed until December 1, 2001, except under
certain circumstances. Prior to December 1, 2001, the 1996 Notes are subject to
redemption, at the option of Allied NA, at prices specified in the indenture. At
any time prior to December 1, 1999, up to 33% of principal amount of the 1996
Notes will be redeemable, at the option of Allied NA, from the proceeds of one
or more public offerings of capital stock by the Company at a redemption price
of 110.25% of principal amount, plus accrued interest. The 1996 Notes are
guaranteed by the Company and substantially all of Allied NA's subsidiaries, the
guarantees of which are expressly subordinated to the guarantees of Allied NA's
Senior Credit Facility.

         During the fourth quarter of 1995, the $5.0 million Convertible
Subordinated Debentures were converted into 1,483,000 shares of Allied common
shares.

         The $5.0 million Senior Convertible Subordinated Debentures bear
interest at 8.5% per annum payable semi-annually, with principal payable in
2002. The debentures are convertible into Allied common shares at $6.00 per
share. Warrants to purchase 195,000 common shares at $6.00 per share were issued
in connection with the sale of the debentures.

         In 1996, the remainder of the 6% Convertible Subordinated Notes were
converted into 362,040 shares of Allied common stock.

         The 8% Convertible note payable to an individual is payable quarterly
through September 1996. Beginning October 1996, principal and interest is
payable in equal monthly installments through October 2006. The note is
convertible into Allied common stock at $10.00 per share during the period of
January 1997 to December 1998.

Debt covenants --

         The Company's Senior Credit Facility, the indenture relating to the
1996 Notes and certain subordinated convertible debt, contain warranties and
covenants, requiring the maintenance of certain tangible net worth, debt to
equity, and cash flow to debt ratios. Additionally, these covenants limit among
other things, the ability of the Company to incur additional secured
indebtedness, make acquisitions and purchase fixed assets above certain amounts,
transfer or sell assets, pay dividends except on certain preferred stock, make
optional payments on certain subordinated indebtedness including the 1996 Notes
or make certain other restricted payments, create liens, enter into certain
transactions with affiliates or consummate a merger, consolidation or sale of
all or substantially all of its assets. At December 31, 1996, Allied was in
compliance with all applicable covenants.

6.    CLOSURE, POST-CLOSURE AND ENVIRONMENTAL COSTS

         The net present value of the closure and post-closure commitment is
calculated assuming inflation of 3.5% and a risk-free capital rate of 7.0%.
Discounted amounts previously recorded are accreted to reflect the effects of
the passage of time. The Company's current estimate of total future payments for
closure and post-closure is $467 million, as shown below, while the present
value of such estimate is $181 million. At December 31, 1995 and 1996,
respectively, accruals for landfill closure, post-closure and environmental
costs (including costs assumed through acquisitions) were approximately $10.5
million and $152.5 million. The accruals reflect relatively young landfills
whose estimated remaining lives, based on current waste flows, range from 1 to
over 75 years, with an estimated average remaining life of greater than 30
years.

</TABLE>

         During 1994, the Company's landfills became subject to the closure and
post-closure requirements of Subtitle D. Previously, the Company's landfills
were subject to local requirements. The principal changes under Subtitle D are
an extension of the post-closure monitoring period to 30 years, more rigorous
groundwater monitoring, and a requirement to use clay or synthetic liners as
capping materials. The Company updated its estimates of future closure and
post-closure costs in accordance with its interpretations of Subtitle D.

         In connection with the Laidlaw Acquisition, Allied engaged an
independent environmental consulting firm to assist in conducting an
environmental assessment of the real property owned by the acquired subsidiaries
or third-parties, and properties under the management of the acquired companies.
Several contaminated landfills and other properties have been identified, two of
which are owned by subsidiaries of the Company, that would require those
subsidiaries to incur costs for incremental closure and post-closure measures,
remediation activities and litigation costs. The costs of performing the
investigation, design, remediation and the allocation of responsibility to the
subsidiaries of Allied vary significantly between sites. Based on information
available to the Company, Allied recorded a provision of $51.5 million for
environmental matters, including closure and post-closure costs, in the 1996
statement of operations and expects these amounts to be disbursed over the next
30 years.

         Prior to the Company's acquisition of CRX, an investigation of an
unrelated manufacturing facility led to allegations that hazardous wastes were
transported to and disposed of in CRX's Norfolk, Nebraska landfill. A provision
of $2.1 million, in excess of the closure and post-closure reserves recorded in
the normal course of business, was made in the Company's 1994 consolidated
financial statements to recognize the estimated costs of additional closure,
post-closure and remedial measures. Since 1994 the Company has engaged an
independent environmental consultant to assist it in conducting the groundwater
contamination investigation program. Based on a report from the Company's
independent environmental consultant an additional provision of $2.0 million has
been recorded in the 1996 statements of operations. The groundwater
investigation is ongoing and remediation efforts have commenced.

         The ultimate amounts for environmental liabilities cannot be determined
and estimates of such liabilities made by the Company, after consultation with
its independent environmental engineers, require assumptions about future events
due to a number of uncertainties including the extent of the contamination, the
appropriate remedy, the financial viability of other potentially responsible
parties and the final apportionment of responsibility among the potentially
responsible parties. Where the Company has concluded that its estimated share of
potential liabilities is probable, a provision has been made in the consolidated
financial statements. Since the ultimate outcome of these matters may differ
from the estimates used in the Company's assessment to date, the recorded
liabilities will be periodically evaluated as additional information becomes
available to ascertain that the accrued liabilities are adequate. The Company
has determined that the recorded liability for environmental matters as of
December 31, 1996 of approximately $152.5 million represents the most probable
outcome of these contingent matters. The Company does not expect that
adjustments to estimates, which are reasonably possible in the near term and
that may result in changes to recorded amounts, will have a material effect on
the Company's consolidated liquidity, financial positions or results of
operations.

          On January 30, 1995, all Series E preferred was converted into common
stock. In December 1995, all of the Series C preferred stock and $90 preferred
stock was converted into common stock. During 1996, all of the Series D
preferred stock and 9% preferred stock was converted into Common Stock.

  7% cumulative convertible preferred stock --

         In April 1994, Allied issued 9,982 shares of 7% cumulative convertible
stock ("7% preferred") in connection with the acquisition of Southern States
Environmental Services. The stock has no voting rights and is redeemable at the
option of the Company under certain conditions. The stock is convertible into
common stock at a rate equal to $7.00 per common share subject to anti-dilution
provisions. Dividends are $70.00 per share per annum, cumulative and payable
quarterly in common stock through April 15, 1995 and in cash thereafter.

In connection with the Laidlaw Acquisition, the Company issued a warrant to
Laidlaw for the purchase of 20,400,000 shares of Common Stock at an exercise
price of $8.25 per share. Both the number of shares purchasable upon exercise of
the warrant and the exercise price are subject to adjustment under certain
circumstances described in the warrant. Among other restrictions, Laidlaw and
its affiliates are precluded from exercising the warrant unless there is a
change of control of Allied. Laidlaw may sell the warrant to third-parties,
provided that any such third-party and its affiliates do not beneficially own
more than 9% of the Company's then outstanding Common Stock. The warrant expires
December 2008.


8.  STOCK OPTION PLANS

         The 1991 Incentive Stock Plan ("1991 Plan"), the 1993 Incentive Stock
Plan ("1993 Plan") and the 1994 Incentive Stock Plan ("1994 Plan") provide for
the grant of non-qualified stock options, incentive stock options, shares of
restricted stock, shares of phantom stock and stock bonuses. The maximum number
of shares which may be granted under the 1991 Plan may not exceed the greater of
750,000 common shares or 7.5% of the number of common shares outstanding at the
end of a preceding fiscal quarter (4,463,778 shares at December 31, 1996). An
additional 500,000 and 1,000,000 common shares may be granted under the 1993
Plan and the 1994 Plan, respectively. The exercise price, term and other
conditions applicable to each option granted are generally determined by the
Compensation Committee of the Board of Directors.

         The 1994 Amended and Restated Non-Employee Director Stock Option Plan
provides for the grant of non-qualified options to each member of the Board of
Directors, who is not also an employee of the Company, at a price equal to the
fair market value of a common share on the date of grant. The maximum number of
shares which may be granted under the plan is 750,000 common shares. All options
granted under the plan are fully vested and exercisable on the date of grant and
expire ten years from the grant date.

         The Company accounts for its stock-based compensation plans under APB
No. 25, under which no compensation expense has been recognized, as all options
have been granted with an exercise price equal to the fair value of the
Company's common stock upon the date of grant. In 1996, the Company adopted SFAS
No. 123 for disclosure purposes and accordingly, the fair value of each option
grant has been estimated as of the date of grant using the Black-Scholes option
pricing model with the following weighted average assumptions: risk-free
interest rate of 5.18% to 7.64%, expected life of 5-8 years, dividend rate of
zero percent, and expected volatility of 49.09% to 52.04%. Using these
assumptions, the impact on the Company's net income (loss) and net income (loss)
per share would not have been material.

are exercisable (iv) 1,653,017 options have exercise prices between $4.27 and
$9.50 and a weighted average remaining contractual life of 8.9 years, of which
none are exercisable.

9.  NET INCOME (LOSS) PER COMMON SHARE

         Net income (loss) per common share is calculated by dividing net income
(loss), less dividend requirements on preferred stock, by the weighted average
number of common shares and common share equivalents outstanding during each
period as restated to reflect acquisitions accounted for as
poolings-of-interests. The computation of weighted average common and common
equivalent shares used in the calculation of net income (loss) per common share
is as follows:

10.  INCOME TAXES

         The Company accounts for income taxes using a balance sheet approach
whereby deferred tax assets and liabilities are determined based on the
differences in financial reporting and income tax basis of assets, other than
goodwill, and liabilities, and the differences are measured using the income tax
rate in effect in the year of measurement.

         The Company and its subsidiaries file a consolidated federal income tax
return. As of December 31, 1996, Allied had a net operating loss carryforward
("NOLC") for federal income tax purposes and state income tax purposes of
approximately $15.2 and $7.0 million, respectively. The NOLCs, which expire
beginning in 2004, are available to offset future taxable income subject to
potential limitations. Included in the NOLCs are losses of acquired companies
which the Company believes are realizable after application of change of
ownership and separate return loss year limitation rules. The Company has placed
a valuation reserve on "other" NOLCs to reflect limitations from separate
Company filing rules. These "other" NOLCs are not included in the amounts above.

The components of the income tax provision (benefit) consist of the following
(in thousands):

</TABLE>

Tax benefits on the extraordinary items in 1994 and 1996 were based on the
Company's then ordinary combined federal and state rate of 38.5% and 40%,
respectively.

         The net current deferred tax asset of $2.7 million and $5.8 million, as
of December 31, 1995 and 1996, respectively, consists of the current benefit
expected to be obtained from the utilization of the Company's NOLCs and its
alternative minimum tax credits. These amounts include a valuation allowance of
$1.2 million and $1.3 million, as of December 31, 1995 and 1996, respectively,
to reflect possible limitations on the ability to use NOLCs for separate company
federal and state filing purposes.

         The increase in the long-term deferred tax liability includes deferred
taxes related to 1996 acquisitions where the financial basis of assets acquired
exceeded the tax basis of those assets.

11.  COMMITMENTS AND CONTINGENCIES

         The Company is subject to extensive and evolving laws and regulations
and has implemented its own environmental safeguards to respond to regulatory
requirements. In the normal course of conducting its operations, Allied may
become involved in certain legal and administrative proceedings. Some of these
actions may result in fines, penalties or judgements against the Company which
may have an impact on earnings for a particular period. Management expects that
such matters in process at December 31, 1996 which have not been accrued in the
consolidated balance sheet will not have a material adverse effect on the
Company's consolidated liquidity, financial position or results from operations.

         The consolidated federal income tax returns for the fiscal years ended
August 31, 1986, 1987 and 1988 of certain subsidiaries of the Company that were
acquired from Laidlaw in December 1996 (the "LSW Subsidiaries") have been under
audit by the Internal Revenue Service. In March 1994, the LSW Subsidiaries
received a Statutory Notice of Deficiency proposing that the LSW Subsidiaries
pay additional taxes relating to disallowed deductions in those income tax
returns (the "Tax Controversy"). The consolidated tax group of the LSW
Subsidiaries has also received notice that fiscal years 1992, 1993 and 1994 will
be examined regarding the Tax Controversy. The LSW Subsidiaries could be
directly liable for a substantial portion of any tax and interest assessed if
the disallowance of the deduction is sustained. In addition, under Treasury
Regulations promulgated under Section 1502 of the Internal Revenue Code ("IRC"),
each member of the consolidated tax group including each LSW Subsidiary, is or
could be severally liable for federal income tax liabilities of the entire
consolidated tax group, including any taxes due on the deemed sale of assets by
the LSW Subsidiaries pursuant to Section 338 of the IRC and all amounts at issue
in the Tax Controversy which are ultimately determined to be owed.

         Any amounts at issue in the Tax Controversy and for which any LSW
Subsidiary may ultimately be found liable, are included in and covered by the
indemnification of the Company by Laidlaw set forth in the Stock Purchase
Agreement by and between the Company and Laidlaw, among others, dated September
17, 1996 (the "Purchase Agreement"). Further, the Company and Laidlaw, among
others, have entered into a Setoff Agreement, under which Laidlaw has agreed
that if the Tax Controversy results in any damage, liability or expense to any
LSW Subsidiary, and if Laidlaw fails to indemnify the Company against all such
damages, liabilities or expenses within 30 days of a demand for indemnification,
then the Company may set off the amount of all such damages, liabilities

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

and expenses against all amounts then owed by the Company under the certain debt
issued to Laidlaw consisting primarily of the Allied Canada Debentures.

         Other than to the extent contemplated in the Setoff Agreement, the
obligation of Laidlaw to indemnify the Company in respect of amounts at issue in
the Tax Controversy is a general, unsecured obligation of Laidlaw. The ability
of Laidlaw to pay and fulfill such indemnification obligation will depend on the
financial condition of Laidlaw at the time of any required performance of such
obligation.

         In connection with certain acquisitions, the Company has entered into
agreements to pay royalties based on waste tonnage disposed at specified
landfills. The royalties are payable quarterly and the current amounts due are
included in the accompanying consolidated balance sheets. Additionally, the
Company has entered into a deferred royalty agreement of which the liability may
be converted into an interest bearing note or common shares.

         Allied has operating lease agreements for service facilities, office
space and equipment. Future minimum payments under non-cancelable operating
leases with terms in excess of one year are as follows (in thousands):

</TABLE>

Rental expense under such operating leases was $1,307,000, $2,775,000 and
$6,476,047 for the three years ended December 31, 1996, respectively.

         The Company has entered into employment agreements with certain of its
executive officers for periods up to five years. The Company has agreed to
severance pay amounts equal to a multiple of defined compensation under certain
circumstances. In the event of a material change in control or termination of
all executive officers under such agreements, Allied would be required to make
payments of approximately $5.5 million.

         Allied carries a broad range of insurance coverage for protection of
its assets and operations from certain risks including environmental impairment
liability insurance for certain landfills.

         The Company has issued bank letters-of-credit, performance bonds and
other guarantees in the aggregate amount of approximately $53.7 million. These
financial instruments are issued in the normal course of business and are not
reflected in the accompanying balance sheets. Such financial instruments are to
be valued based on the amount of exposure under the instrument and the
likelihood of performance being required. Management does not expect any
material losses to result from these off balance sheet instruments based on
historical results, and therefore, is of the opinion that the fair value of
these instruments is zero.

12.  RELATED PARTY TRANSACTIONS

         Transactions with related parties are entered into only upon approval
by a majority of the independent directors of the Company and only upon terms
comparable to those that would be available from unaffiliated parties.

         The Company leases certain properties and equipment in Illinois from
related parties resulting from prior year acquisitions. In connection with these
leases, payments of $89,000, $69,000 and $45,000 for the three years ended
December 31, 1996, respectively, were made to officers of the Company.

         In connection with certain acquisitions, previous owners are paid an
agreed upon amount not to compete with the Company. Annual payments of $88,000,
were made to officers of the Company for each of the three years ended December
31, 1996 related to these non-compete agreements.

         In connection with certain acquisitions, previous owners agreed to
continue their existing personal guarantees on assumed indebtedness for a fee.
Payments of $20,000 were made to an officer of the Company for the year ended
December 31, 1994.

         A Director is a partner in the firm which serves as the Company's
principal legal counsel.

         During 1994, the Company purchased real property from an officer for
approximately $1 million. The real property was subsequently exchanged for a
transfer station and a materials recovery facility in the Chicago area
previously owned by an unrelated party. No gain or loss was recognized on the
exchange.

         The Company made payments of $191,000 and $254,000 in 1994 and 1995,
respectively, on a life insurance policy for a related party assumed in a 1994
acquisition. A trust of the related party is the beneficiary of the policy.

         In connection with the receipt in April 1995 of all permits necessary
to develop a landfill on certain real estate acquired in July 1992, the Company
was obligated to pay $5.6 million to the previous owners of the real estate,
including current stockholders of the Company. During the years ended December
31, 1995 and 1996, the Company paid $924,000 and $121,000, respectively, to
these stockholders. The Company has $1.9 million in promissory notes payable to
these stockholders outstanding at December 31, 1996.

or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

        8.2  The corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor by reason of the fact that he is or was a director, officer, employee
or agent of 


                                       2

the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the court shall deem proper.

     8.3 To the extent that a director, officer, employee or agent of a
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in Sections 8.1 and 8.2 of this Article,
or in defense of any claim, issue or matter therein, the corporation shall
indemnify such director, officer, employee or agent against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection
therewith.

     8.4 Any indemnification under Sections 8.1 and 8.2 of this Article (unless
ordered by a court) shall be made by the corporation only as authorized in the
specific case upon a determination that indemnification of the director,
officer, employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Sections 8.1 and 8.2 of this
Article. Such determination shall be made (1) by the board of directors by a
majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding, or (2) if such a quorum is not obtainable, or, even
if obtainable a quorum of disinterested directors so directs, by independent
legal counsel in a written opinion, or (3) by the stockholders.

     8.5 Expenses incurred by an officer or director in defending a civil or
criminal action, suit or proceeding shall be paid by the corporation in advance
of the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the corporation as authorized in this Article. Such expenses incurred by other
employees and agents shall be so paid upon such terms and conditions, if any, as
the board of directors deems appropriate.

     8.6 The indemnification and advancement of expenses provided by, or granted
pursuant to, this Article shall not be deemed exclusive of any other rights to
which those seeking indemnification or advancement of expenses may be entitled
under any bylaw, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in an official capacity and as to action in another
capacity while holding such office.

     8.7 The corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint


                                       3

venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the corporation would have the power to indemnify him against
such liability under the General Corporation Law of the State of Delaware or
this Article.

        8.8  For purposes of this Article, references to "the Corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article with
respect to the resulting or surviving corporation as he would have with respect
to such constituent corporation if its separate existence had continued.

        8.9  For purposes of this Article, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on a person with respect to any employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee or
agent with respect to an employee benefit plan, its participants or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the corporation" as referred to in this
section.

        8.10  The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article shall continue as to a person who has ceased
to be a director, officer, employee or agent and shall inure to the benefit of
the heirs, executors and administrators of such a person.

                                   ARTICLE IX

        Whenever a compromise or arrangement is proposed between the
corporation and its creditors or any class of them and/or between the
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the corporation under
the provisions of section 291 of the General Corporation Law of the State of
Delaware or on the application of trustees in dissolution or of any receiver or
receivers appointed for the corporation under the provisions of section 279 of
the General Corporation Law of the State of Delaware, order a meeting of the
creditors or class of creditors, and/or of the stockholders or class of
stockholders of the corporation, as the case may be, to be summoned in such
manner as the court directs. If a majority in number, representing
three-fourths in value, of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of the corporation, as the 


                                       4

<PAGE>   5
case may be, agree to any compromise or arrangement and to any reorganization
of the corporation as a consequence of such compromise or arrangement and the
said reorganization shall, if sanctioned by the court to which the said
application has been made, be binding on all the creditors or class of
creditors, and/or on all of the stockholders or class of stockholders, of the
corporation, as the case may be, and also on the corporation.

                                   ARTICLE X

        The corporation is to have perpetual existence.

                                   The Credits

         SECTION 2.01. Commitments. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, (a) to make Term Loans to the Borrower on the
Closing Date in an aggregate principal amount not to exceed its Term Loan
Commitment, (b) to make AXELs Series A Loans to the Borrower on the Closing Date
in an aggregate principal amount not to exceed its AXELs Series A Commitment,
(c) to make AXELs Series B Loan to the Borrower on the Closing Date in an
aggregate principal amount not to exceed its AXELs Series B Commitment, (d) to
make AXELs Series C Loans to the Borrower on the Closing Date in an aggregate
principal amount not to exceed its AXELs Series C Commitment, (e) to make
Revolving Loans to the Borrower, at any time and from time to time on or after
the date hereof, and until the earlier of the Revolving Credit Maturity Date (or
in the case of Acquisition Loans, the Acquisition Loan Termination Date) and the
termination of the Revolving Credit Commitment of such Lender in accordance with
the terms hereof, in an aggregate principal amount at any time outstanding that
will not result in (x) (i) such Lender's Revolving Credit Exposure exceeding
(ii) such Lender's Revolving Credit Commitment or (y) the aggregate principal
amount of all Acquisition Loans at any time outstanding exceeding $100,000,000.
Within the limits set forth in clause (e) of the preceding sentence and subject
to the terms, conditions and limitations set forth herein, the Borrower may
borrow, pay or prepay and reborrow Revolving Loans. Amounts paid or prepaid in
respect of Term Loans or AXELs Loans may not be reborrowed.

         SECTION 2.02. Loans. (a) Each Loan (other than Swingline Loans) shall
be made as part of a Borrowing consisting of Loans made by the Lenders ratably
in accordance with their respective Revolving Credit Commitments, Term Loan
Commitments, AXELs Series A Commitments, AXELs Series B Commitments or AXELs
Series C Commitments, as applicable; provided, however, that the failure of any
Lender to make any Loan shall not in itself relieve any other Lender of its
obligation to lend hereunder (it being understood, however, that no Lender shall
be responsible for the failure of any other Lender to make any Loan required to
be made by such other Lender). Except for Loans deemed made pursuant to Section
2.02(f), the Loans comprising any Borrowing shall be in an aggregate principal
amount that is (i) an integral multiple of $1,000,000 and not less than
$5,000,000 or (ii) equal to the remaining available balance of the applicable
Commitments.

         (b) Subject to Sections 2.08 and 2.15, each Borrowing shall be
comprised entirely of Base Rate Loans or Eurodollar Loans as the Borrower may
request pursuant to Section 2.03. Each Lender may at its option make any
Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such
Lender to make such Loan; provided that any exercise of such option shall not
affect the obligation of the Borrower to repay such Loan in accordance with the
terms of this Agreement. Borrowings of more than one Type may be outstanding at
the same time; provided, however, that the Borrower shall not be entitled to
request any Borrowing that, if made, would result in more than 20 Eurodollar
Borrowings outstanding hereunder at any time. For purposes of the foregoing,
Borrowings having different Interest Periods, regardless of whether they
commence on the same date, shall be considered separate Borrowings.
<PAGE>   37
                                                                              31





         (c) Except with respect to Loans made pursuant to Section 2.02(f), each
Lender shall make each Loan to be made by it hereunder on the proposed date
thereof by wire transfer of immediately available funds to such account in New
York City as the Administrative Agent may designate not later than 12:00 (noon),
New York City time, and the Administrative Agent shall by 1:00 p.m., New York
City time, credit the amounts so received to an account in the name of the
Borrower designated by the Borrower in the applicable Borrowing Request or, if a
Borrowing shall not occur on such date because any condition precedent herein
specified shall not have been met, return the amounts so received to the
respective Lenders.

         (d) Unless the Administrative Agent shall have received notice from a
Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's portion of such Borrowing,
the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, such Lender and the Borrower severally
agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Administrative Agent at (i) in the case of the Borrower, the
interest rate applicable at the time to the Loans comprising such Borrowing and
(ii) in the case of such Lender, for the first such day, the Federal Funds
Effective Rate, and for each day thereafter, the Base Rate. If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement, and the Borrower shall be relieved of its obligation pursuant to the
preceding sentence to repay such amount or, if such amount has theretofore been
repaid by the Borrower to the Administrative Agent, the Administrative Agent
shall make such corresponding amount available to the Borrower.

         (e) Notwithstanding any other provision of this Agreement, the Borrower
shall not be entitled to request any Revolving Credit Borrowing, Term Borrowing,
AXELs Series A Borrowing, AXELs Series B Borrowing or AXELs Series C Borrowing
if the Interest Period requested with respect thereto would end after the
Revolving Credit Maturity Date (or in the case of an Acquisition Borrowing, the
Acquisition Loan Repayment Date), the Term Loan Maturity Date, the AXELs Series
A Maturity Date, the AXELs Series B Maturity Date or the AXELs Series C Maturity
Date, respectively.

         (f) If the Issuing Bank shall not have received from the Borrower or
Allied, as the case may be, the payment required to be made by Section 2.23(e)
within the time specified in such Section, the Issuing Bank will promptly notify
the Administrative Agent of the L/C Disbursement and the Administrative Agent
will promptly notify each Revolving Credit Lender of such L/C Disbursement and
its Pro Rata Percentage thereof. Each Revolving Credit Lender shall pay by wire
transfer of immediately available funds to the Administrative Agent not later
than 2:00 p.m., New York City time, on such date (or, if such Revolving Credit
Lender shall have received such notice later than 12:00 (noon), New York City
time, on any day, not later than 12:00 (noon), New York City time, on the
immediately following Business Day), an amount equal to such Lender's Pro Rata
Percentage of such L/C Disbursement (it being understood that such amount
<PAGE>   38
                                                                              32





shall be deemed to constitute a Base Rate Revolving Loan of such Lender and such
payment shall be deemed to have reduced the L/C Exposure), and the
Administrative Agent will promptly pay to the Issuing Bank amounts so received
by it from the Revolving Credit Lenders. The Administrative Agent will promptly
pay to the Issuing Bank any amounts received by it from the Borrower pursuant to
Section 2.23(e) prior to the time that any Revolving Credit Lender makes any
payment pursuant to this paragraph (f); any such amounts received by the
Administrative Agent thereafter will be promptly remitted by the Administrative
Agent to the Revolving Credit Lenders that shall have made such payments and to
the Issuing Bank, as their interests may appear. If any Revolving Credit Lender
shall not have made its Pro Rata Percentage of such L/C Disbursement available
to the Administrative Agent as provided above, such Lender and the Borrower or
Allied, as the case may be, severally agree to pay interest on such amount, for
each day from and including the date such amount is required to be paid in
accordance with this paragraph to but excluding the date such amount is paid, to
the Administrative Agent for the account of the Issuing Bank at (i) in the case
of the Borrower or Allied, as the case may be, a rate per annum equal to the
interest rate applicable to Revolving Loans pursuant to Section 2.06(a), and
(ii) in the case of such Lender, for the first such day, the Federal Funds
Effective Rate, and for each day thereafter, the Base Rate.

         SECTION 2.03. Borrowing Procedure. In order to request a Borrowing
(other than a Swingline Loan or a deemed Borrowing pursuant to Section 2.02(f),
as to which this Section 2.03 shall not apply), the Borrower shall hand deliver
or telecopy to the Administrative Agent a duly completed Borrowing Request (a)
in the case of a Eurodollar Borrowing, not later than 11:00 a.m., New York City
time, three Business Days before a proposed Borrowing, and (b) in the case of a
Base Rate Borrowing, not later than 12:00 noon, New York City time, one Business
Day before a proposed Borrowing. Each Borrowing Request shall be irrevocable,
shall be signed by or on behalf of the Borrower and shall specify the following
information: (i) whether the Borrowing then being requested is to be a Term
Borrowing, an AXELs Series A Borrowing, an AXELs Series B Borrowing, an AXELs
Series C Borrowing or a Revolving Credit Borrowing (and, if a Revolving Credit
Borrowing, whether such Borrowing is an Acquisition Borrowing), and whether such
Borrowing is to be a Eurodollar Borrowing or a Base Rate Borrowing; (ii) the
date of such Borrowing (which shall be a Business Day), (iii) the number and
location of the account to which funds are to be disbursed (which shall be an
account that complies with the requirements of Section 2.02(c)); (iv) the amount
of such Borrowing; and (v) if such Borrowing is to be a Eurodollar Borrowing,
the Interest Period with respect thereto; provided, however, that, (x)
notwithstanding any contrary specification in any Borrowing Request, each
requested Borrowing shall comply with the requirements set forth in Section 2.02
and (y) upon the request of the Syndication Agent, the Administrative Agent and
the Documentation Agent, during the period from and including the Closing Date
to but excluding a date not more than 60 days after the Closing Date, the
Borrower shall not be entitled to elect to make Eurodollar Borrowings. If no
election as to the Type of Borrowing is specified in any such notice, then the
requested Borrowing shall be a Base Rate Borrowing. If no Interest Period with
respect to any Eurodollar Borrowing is specified in any such notice, then the
Borrower shall be deemed to have selected an Interest Period of one month's
duration. The Administrative Agent shall promptly advise the applicable Lenders
of any notice given pursuant to this Section 2.03 (and the contents thereof),
and of each Lender's portion of the requested Borrowing.

each Term Loan, AXELs Loan and Acquisition Loan of such Lender as provided in
Section 2.11 and (iii) the then unpaid principal amount of each Revolving Loan
on the Revolving Credit Maturity Date.

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Loan made by such Lender from time to time, including the
amounts of principal and interest payable and paid such Lender from time to time
under this Agreement.

         (c) The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder from the Borrower or any Guarantor and each Lender's share thereof.

         (d) The entries made in the accounts maintained pursuant to paragraphs
(b) and (c) above shall be prima facie evidence of the existence and amounts of
the obligations therein recorded; provided, however, that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligations of the Borrower to repay
the Loans in accordance with their terms.

         (e) Notwithstanding any other provision of this Agreement, in the event
any Lender shall request and receive a promissory note payable to such Lender
and its registered assigns, the interests represented by such note shall at all
times (including after any assignment of all or part of such interests pursuant
to Section 9.04) be represented by one or more promissory notes payable to the
payee named therein or its registered assigns.

Lender shall expire or be terminated as provided herein, a commitment fee (a
"Commitment Fee") equal to the Applicable Percentage per annum in effect from
time to time on the average daily unused amount of the Commitments of such
Lender (other than the Swingline Commitment) during the preceding quarter (or
other period commencing with the date of acceptance by the Borrower of the
Commitment of such Lender or ending with the Revolving Credit Maturity Date or
the date on which the Commitments of such Lender shall expire or be terminated).
All Commitment Fees shall be computed on the basis of the actual number of days
elapsed in a year of 360 days. The Commitment Fee due to each Lender shall
commence to accrue on the date such Lender's Commitment was allocated to such
Lender by the Syndication Agent, the Administrative Agent and the Documentation
Agent and shall cease to accrue on the date on which the Commitment of such
Lender shall expire or be terminated as provided herein. For purposes of
calculating Commitment Fees only, no portion

of the Revolving Credit Commitments shall be deemed utilized under Section 2.17
as a result of outstanding Swingline Loans.

         (b) The Borrower agrees to pay to the Administrative Agent, for its own
account, the administrative fees set forth in the Fee Letters at the times and
in the amounts specified therein (the "Administrative Agent Fees").

         (c) The Borrower agrees to pay (i) to each Revolving Credit Lender,
through the Administrative Agent, on the last Business Day of March, June,
September and December of each year, commencing the last Business Day of March
1997, and on the date on which the Revolving Credit Commitment of such Lender
shall be terminated as provided herein, a fee (an "L/C Participation Fee")
calculated on such Lender's Pro Rata Percentage of the average daily aggregate
L/C Exposure (excluding the portion thereof attributable to unreimbursed L/C
Disbursements) during the quarter ending on such date (or shorter period
commencing with the date hereof or ending with the Revolving Credit Maturity
Date or the date on which all Letters of Credit have been canceled or have
expired and the Revolving Credit Commitments of all Lenders shall have been
terminated) at a rate equal to the Applicable Percentage from time to time used
to determine the interest rate on Revolving Credit Borrowings comprised of
Eurodollar Loans pursuant to Section 2.06, and (ii) to the Issuing Bank with
respect to each Letter of Credit (x) a fronting fee equal to 1/4 of 1% per annum
of the outstanding face amount of such Letter of Credit, payable quarterly in
arrears and (y) the standard issuance and drawing fees specified from time to
time by the Issuing Bank (the "Issuing Bank Fees"). All L/C Participation Fees
and Issuing Bank Fees shall be computed on the basis of the actual number of
days elapsed in a year of 360 days.

         All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the Lenders, except that the Issuing Bank Fees shall be paid directly to
the Issuing Bank. Once paid, none of the Fees shall be refundable under any
circumstances.

         SECTION 2.06. Interest on Loans. (a) Subject to the provisions of
Section 2.07, the Loans comprising each Base Rate Borrowing, including each
Swingline Loan, shall bear interest (computed on the basis of the actual number
of days elapsed over a year of 365 or 366 days, as the case may be, when the
Base Rate is determined by reference to the Prime Rate and over a year of 360
days at all other times) at a rate per annum equal to (i) in the case of
Revolving Credit Borrowings and Term Borrowings, the Base Rate plus the
Applicable Percentage in effect from time to time, (ii) in the case of AXELs
Series A Borrowings, the Base Rate plus 1.75%, (iii) in the case of AXELs Series
B Borrowings, the Base Rate plus 2.00% and (iv) in the case of AXELs Series C
Borrowings, the Base Rate plus 2.25%.

         (b) Subject to the provisions of Section 2.07, the Loans comprising
each Eurodollar Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 360 days) at a rate per annum equal
to (i) in the case of Revolving Credit Borrowings and Term Borrowings, the
Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the
Applicable Percentage in effect from time to time, (ii) in the case of AXELs
Series A Borrowings, the Adjusted LIBO Rate for the Interest Period in effect
for such Borrowing plus 2.75%, (iii) in the case of AXELs Series B Borrowings,
the Adjusted LIBO Rate

                                                                              35





for the Interest Period in effect for such Borrowing plus 3.00% and (iv) in the
case of AXELs Series C Borrowings, the Adjusted LIBO Rate for the Interest
Period in effect for such Borrowing plus 3.25%.

         (c) Interest on each Loan shall be payable on the Interest Payment
Dates applicable to such Loan except as otherwise provided in this Agreement.
The applicable Base Rate or Adjusted LIBO Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by the
Administrative Agent, and such determination shall be conclusive absent manifest
error.

         SECTION 2.07. Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, by acceleration or otherwise, or under any other Loan Document,
the Borrower shall on demand from time to time pay interest, to the extent
permitted by law, on such defaulted amount to but excluding the date of actual
payment (after as well as before judgment) (a) in the case of overdue principal,
at the rate otherwise applicable to such Loan pursuant to Section 2.06 plus
2.00% per annum and (b) in all other cases, a rate per annum (computed on the
basis of the actual number of days elapsed over a year of 365 or 366 days, as
the case may be, when determined by reference to the Prime Rate and over a year
of 360 days at all other times) equal to the sum of the Base Rate plus the
Applicable Percentage applicable to Base Rate Loans plus 2.00%.

         SECTION 2.08. Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined that dollar deposits in the principal amounts of the Loans comprising
such Borrowing are not generally available in the London interbank market, or
that the rates at which such dollar deposits are being offered will not
adequately and fairly reflect the cost to any Lender of making or maintaining
its Eurodollar Loan during such Interest Period, or that reasonable means do not
exist for ascertaining the Adjusted LIBO Rate, the Administrative Agent shall,
as soon as practicable thereafter, give written or telecopy notice of such
determination to the Borrower and the Lenders. In the event of any such
determination, until the Administrative Agent shall have advised the Borrower
and the Lenders that the circumstances giving rise to such notice no longer
exist, any request by the Borrower for a Eurodollar Borrowing pursuant to
Section 2.03 or 2.10 shall be deemed to be a request for a Base Rate Borrowing.
Each determination by the Administrative Agent hereunder shall be conclusive
absent manifest error.

         SECTION 2.09. Termination and Reduction of Commitments. (a) Each
Lender's Term Loan Commitment and AXELs Commitment, as applicable, shall
terminate (i) at the time such Lender makes the Term Loans or AXELs Loans, as
applicable, to be made by it on the Closing Date in accordance with Section 2.01
or (ii) in the event any such Lender reasonably determines that the conditions
precedent set forth in Section 4.02 have not be satisfied on or prior to the
Closing Date, at 5:00 p.m., New York City time, on the Closing Date. The
Revolving Credit Commitments, the Swingline Commitment and the L/C Commitment
shall automatically terminate on the Revolving Credit Maturity Date.
Notwithstanding the foregoing, all the Commitments shall automatically terminate
at 5:00 p.m., New York City time, on February 28, 1997, if the initial Credit
Event shall not have occurred by such time.

                                                                              36





         (b) Upon at least five Business Days' prior irrevocable written or
telecopy notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Term Loan Commitments, the AXELs Commitments or the Revolving Credit
Commitments; provided, however, that (i) each partial reduction of the Term Loan
Commitments, the AXELs Commitments or the Revolving Credit Commitments shall be
in an integral multiple of $1,000,000 and in a minimum amount of $5,000,000 and
(ii) the Total Revolving Credit Commitment shall not be reduced to an amount
that is less than the Aggregate Revolving Credit Exposure at the time.

         (c) Each reduction in the Term Loan Commitments, the AXELs Commitments
or the Revolving Credit Commitments hereunder shall be made ratably among the
Lenders in accordance with their respective applicable Commitments. The Borrower
shall pay to the Administrative Agent for the account of the applicable Lenders,
on the date of each termination or reduction, the Commitment Fees on the amount
of the Commitments so terminated or reduced accrued to but excluding the date of
such termination or reduction.

         SECTION 2.10. Conversion and Continuation of Borrowings. The Borrower
shall have the right at any time upon prior irrevocable notice to the
Administrative Agent (a) not later than 12:00 (noon), New York City time, one
Business Day prior to conversion, to convert any Eurodollar Borrowing into a
Base Rate Borrowing, (b) not later than 11:00 a.m., New York City time, three
Business Days prior to conversion or continuation, to convert any Base Rate
Borrowing into a Eurodollar Borrowing or to continue any Eurodollar Borrowing as
a Eurodollar Borrowing for an additional Interest Period, and (c) not later than
11:00 a.m., New York City time, three Business Days prior to conversion, to
convert the Interest Period with respect to any Eurodollar Borrowing to another
permissible Interest Period, subject in each case to the following:

                  (i) each conversion or continuation shall be made pro rata
         among the Lenders in accordance with the respective principal amounts
         of the Loans comprising the converted or continued Borrowing;

                 (ii) if less than all the outstanding principal amount of any
         Borrowing shall be converted or continued, then each resulting
         Borrowing shall satisfy the limitations specified in Sections 2.02(a)
         and 2.02(b) regarding the principal amount and maximum number of
         Borrowings of the relevant Type;

                (iii) each conversion shall be effected by each Lender and the
         Administrative Agent by recording for the account of such Lender the
         new Loan of such Lender resulting from such conversion and reducing the
         Loan (or portion thereof) of such Lender being converted by an
         equivalent principal amount; accrued interest on any Eurodollar Loan
         (or portion thereof) being converted shall be paid by the Borrower at
         the time of conversion;

                 (iv) if any Eurodollar Borrowing is converted at a time other
         than the end of the Interest Period applicable thereto, the Borrower
         shall pay, upon demand, any amounts due to the Lenders pursuant to
         Section 2.16;
<PAGE>   43
                                                                              37





                  (v) any portion of a Borrowing maturing or required to be
         repaid in less than one month may not be converted into or continued as
         a Eurodollar Borrowing;

                 (vi) any portion of a Eurodollar Borrowing that cannot be
         converted into or continued as a Eurodollar Borrowing by reason of the
         immediately preceding clause shall be automatically converted at the
         end of the Interest Period in effect for such Borrowing into a Base
         Rate Borrowing;

                (vii) no Interest Period may be selected for any Eurodollar Term
         Borrowing, any Eurodollar AXELs Borrowing or any Eurodollar Borrowing
         comprised of Acquisition Loans that would end later than a Term Loan
         Repayment Date, an AXELs Repayment Date or an Acquisition Loan
         Repayment Date, respectively, occurring on or after the first day of
         such Interest Period if, after giving effect to such selection, the
         aggregate outstanding amount of (A) the Eurodollar Term Borrowings,
         Eurodollar AXELs Borrowings or Eurodollar Borrowings comprised of
         Acquisition Loans, as applicable, with Interest Periods ending on or
         prior to such Term Loan Repayment Date, AXELs Repayment Date or
         Acquisition Loan Repayment Date, respectively, and (B) the Base Rate
         Term Borrowings, the Base Rate AXELs Borrowings and the Base Rate
         Borrowings comprised of Acquisition Loans, as applicable, would not be
         at least equal to the principal amount of Term Borrowings, AXELs
         Borrowings or Acquisition Borrowings, as applicable, to be paid on such
         Term Loan Repayment Date, such AXELs Repayment Date or such Acquisition
         Loan Repayment Date, respectively;

               (viii) after the occurrence and during the continuance of a
         Default or Event of Default, no outstanding Loan may be converted into,
         or continued as, a Eurodollar Loan; and

                 (ix) upon the request of the Syndication Agent, the
         Administrative Agent and the Documentation Agent, during the period
         from and including the Closing Date to but excluding a date not more
         than 60 days after the Closing Date, no Borrowing may be converted into
         a Eurodollar Borrowing.

         Each notice pursuant to this Section 2.10 shall be irrevocable and
shall refer to this Agreement and specify (i) the identity and amount of the
Borrowing that the Borrower requests be converted or continued, (ii) whether
such Borrowing is to be converted to or continued as a Eurodollar Borrowing or a
Base Rate Borrowing, (iii) if such notice requests a conversion, the date of
such conversion (which shall be a Business Day) and (iv) if such Borrowing is to
be converted to or continued as a Eurodollar Borrowing, the Interest Period with
respect thereto. If no Interest Period is specified in any such notice with
respect to any conversion to or continuation as a Eurodollar Borrowing, the
Borrower shall be deemed to have selected an Interest Period of one month's
duration. The Administrative Agent shall advise the Lenders of any notice given
pursuant to this Section 2.10 and of each Lender's portion of any converted or
continued Borrowing. If the Borrower shall not have given notice in accordance
with this Section 2.10 to continue any Borrowing into a subsequent Interest
Period (and shall not otherwise have given notice in accordance with this
Section 2.10 to convert such Borrowing), such Borrowing shall, at the end of the
Interest Period applicable thereto (unless repaid pursuant to
<PAGE>   44
                                                                              38

Base Rate Borrowing.

Lenders, on the dates set forth below, or if any such date is not a Business

"Term Loan Repayment Amount") equal to the amount set forth below for such date,
together in each case with accrued and unpaid interest on the principal amount
to be paid to but excluding the date of such payment:

         (b) In the event and on each occasion that any Term Loan Commitments or
AXELs Commitments shall be reduced or shall expire or terminate other than as a
result of the making of a Term Loan or an AXELs Loan, as applicable, the
installments payable on each Term Loan Repayment Date and AXELs Repayment Date,
as applicable, shall be reduced pro rata by an aggregate amount equal to the
amount of such reduction, expiration or termination.

         (c) To the extent not previously paid, all Term Loans, AXELs Series A
Loans, AXELs Series B Loans, AXELs Series C Loans and Acquisition Loans shall be
due and payable on the Term Loan Maturity Date, AXELs Series A Maturity Date,
AXELs Series B Maturity Date, AXELs Series C Maturity Date and Revolving Credit
Maturity Date, respectively, together with accrued and unpaid interest on the
principal amount to be paid to but excluding the date of payment.

         (d) All repayments pursuant to this Section 2.11 shall be subject to

part, upon at least three Business Days' (in the case of prepayments of Loans
other than AXELs Loans) or five Business Days' (in the case of prepayments of
AXELs Loans) prior written or telecopy notice (or telephone notice promptly
confirmed by written or telecopy notice) to the Administrative Agent before

                                                                              43





reduction shall be in an amount that is an integral multiple of $1,000,000 and
not less than $5,000,000 and (ii) that no Acquisition Loans may be prepaid
pursuant to this Section 2.12(a) if immediately after giving effect to such
prepayment and the prepayment of any other Revolving Loans made concurrently
therewith, any Revolving Loans (other than Acquisition Loans) would be
outstanding.

         (b) Optional prepayments of Term Loans, AXELs Loans or Acquisition
Loans shall be allocated pro rata among the then-outstanding Term Loans, AXELs
Loans or Acquisition Loans and applied pro rata against the remaining scheduled
installments of principal due in respect of the Term Loans, AXELs Loans or
Acquisition Loans under Sections 2.11(a)(i), (ii), (iii), (iv) and (v),
respectively; provided that, on or prior to the Acquisition Loan Termination
Date, the amount of any such prepayment allocated to the outstanding Acquisition
Loans shall be applied to prepay the outstanding Acquisition Loans without
regard to the scheduled amortization thereof.

         (c) Each notice of prepayment shall specify the prepayment date,
whether the Borrowing being prepaid is a Term Borrowing, an AXELs Series A
Borrowing, an AXELs Series B Borrowing, an AXELs Series C Borrowing, an
Acquisition Borrowing or a Revolving Credit Borrowing that is not an Acquisition
Borrowing and the principal amount of each Borrowing (or portion thereof) to be
prepaid, shall be irrevocable and shall commit the Borrower to prepay such
Borrowing by the amount stated therein on the date stated therein. All
prepayments under this Section 2.12 shall be subject to Section 2.16, and
prepayment of AXELs Loans shall be subject to Section 2.12(e), but otherwise
without premium or penalty. All prepayments of Eurodollar Loans under this
Section 2.12 shall be accompanied by accrued interest on the principal amount
being prepaid to the date of payment.

         (d) All prepayments of Acquisition Loans made on or after the
Acquisition Loan Termination Date pursuant to this Section 2.12 shall
automatically and permanently reduce the Total Revolving Credit Commitment by
the amount of such prepayment.

         (e) In the event that the Borrower prepays any AXELs Loan pursuant to
this Section 2.12 on or prior to the Prepayment Premium Date, the Borrower shall
pay on the date such prepayment is made a premium of: (i) 2% of the aggregate
principal amount so prepaid for any such prepayment made on or prior to the
first anniversary of the Closing Date or (ii) 1% of the aggregate principal
amount so prepaid for any such prepayment made after the first anniversary of
the Closing Date but on or prior to the Prepayment Premium Date.

         SECTION 2.13. Mandatory Prepayments. (a) In the event of any
termination of all the Revolving Credit Commitments, the Borrower shall repay or
prepay all its outstanding Revolving Credit Borrowings (other than Acquisition
Borrowings) and all outstanding Swingline Loans on the date of such termination.
In the event of any partial reduction of the Revolving Credit Commitments, then
(i) at or prior to the effective date of such reduction, the Administrative
Agent shall notify the Borrower and the Revolving Credit Lenders of the
Aggregate Revolving Credit Exposure (other than Revolving Credit Exposure with
respect to Acquisition Loans) after giving effect thereto and (ii) if such
Aggregate Revolving Credit Exposure would exceed the Total Revolving Credit
Commitment after giving effect to such reduction or termination, then the
Borrower shall, on the date of such reduction or termination, repay or prepay
Revolving Credit Borrowings (other than Acquisition Borrowings) or Swingline
Loans (or a combination thereof)

                                                                              44





in an amount sufficient to eliminate such excess. If following any reduction of
the Total Revolving Credit Commitment and the payments required by this Section
2.13(a), the Total Revolving Credit Commitment is less than the aggregate L/C
Exposure, the Borrower shall, on the date of such reduction, provide cash
collateral, in accordance with Section 2.23(j), in an amount equal to the amount
that the aggregate L/C Exposure exceeds the Total Revolving Credit Commitment.

         (b) Not later than the third Business Day following the later of (i)
the completion of any Asset Sale and (ii) the receipt of the Net Cash Proceeds
with respect thereto, the Borrower shall apply 100% of the Net Cash Proceeds
received with respect thereto to prepay outstanding Term Loans, AXELs Loans and
Acquisition Loans in accordance with Section 2.13(g).

         (c) Not later than the third Business Day following receipt of any
Extraordinary Amount, the Borrower shall apply 100% of such Extraordinary Amount
received to prepay outstanding Term Loans, AXELs Loans and Acquisition Loans in
accordance with Section 2.13(g).

         (d) In the event and on each occasion that an Equity Issuance occurs,
the Borrower shall, substantially simultaneously with (and in any event not
later than the third Business Day next following) the occurrence of such Equity
Issuance, apply 75% of the Net Cash Proceeds therefrom to prepay outstanding
Term Loans, AXELs Loans and Acquisition Loans in accordance with Section
2.13(g); provided, however, that in the event that the Leverage Ratio as of the
last day of the fiscal quarter most recently ended preceding the date of such
Equity Issuance is less than 2.50 to 1.00, only 50% of such Net Cash Proceeds
shall be required to be so applied pursuant to this clause (d).

         (e) No later than the earlier of (i) 100 days after the end of each
fiscal year of the Borrower, commencing with the fiscal year ending on December
31, 1997, and (ii) the day that is five Business Days after the date on which
the financial statements with respect to such period are delivered pursuant to
Section 5.04(a), the Borrower shall prepay outstanding Term Loans, AXELs Loans
and Acquisition Loans in accordance with Section 2.13(g) in an aggregate
principal amount equal to 75% of Excess Cash Flow for the fiscal year then
ended.

         (f) In the event that Allied, the Borrower or any Subsidiary shall
receive Net Cash Proceeds from the issuance or other disposition of Indebtedness
for money borrowed (other than Indebtedness the issuance of which also
constitutes an Equity Issuance), of Allied, the Borrower or any Subsidiary
(other than Indebtedness for money borrowed permitted pursuant to Section 6.01),
the Borrower shall, substantially simultaneously with (and in any event not
later than the third Business Day next following) the receipt of such Net Cash
Proceeds by Allied, the Borrower or the Subsidiaries, apply an amount equal to
100% of such Net Cash Proceeds to prepay outstanding Term Loans, AXELs Loans and
Acquisition Loans in accordance with Section 2.13(g).

         (g) Mandatory prepayments of outstanding Term Loans, AXELs Loans and
Acquisition Loans under this Agreement shall, subject to paragraph (k) below, be
allocated pro rata among the then-outstanding Term Loans, AXELs Loans and
Acquisition Loans, and, subject to paragraph (j) below, applied pro rata against
the remaining scheduled installments of principal
<PAGE>   51
                                                                              45





due in respect of Term Loans, AXELs Loans and Acquisition Loans under Sections
2.11(a)(i), (ii), (iii), (iv) and (v),as the case may be.

         (h) The Borrower shall deliver to the Administrative Agent, at the time
of each pre-payment required under this Section 2.13, (i) a certificate signed
by a Financial Officer of the Borrower setting forth in reasonable detail the
calculation of the amount of such prepayment and (ii) to the extent practicable,
at least three days prior written notice of such prepayment. Each notice of
prepayment shall specify the prepayment date, the Type of each Loan being
prepaid and the principal amount of each Loan (or portion thereof) to be
prepaid. All prepayments under this Section 2.13 shall be subject to Section
2.16, but shall otherwise be without premium or penalty.

         (i) Amounts to be applied pursuant to this Section 2.13 to the
prepayment of Term Loans, AXELs Loans and Acquisition Loans shall be applied, as
applicable, first to reduce outstanding Base Rate Term Loans, Base Rate AXELs
Loans and Base Rate Acquisition Loans. Any amounts remaining after each such
application shall, at the option of the Borrower, be applied to prepay
Eurodollar Term Loans, Eurodollar AXELs Loans or Eurodollar Acquisition Loans,
as the case may be, immediately and/or shall be deposited in the Prepayment
Account (as defined below). The Administrative Agent shall apply any cash
deposited in the Prepayment Account (i) allocable to Term Loans to prepay
Eurodollar Term Loans, (ii) allocable to AXELs Loans to prepay Eurodollar AXELs
Loans and (iii) allocable to Acquisition Loans to prepay Eurodollar Acquisition
Loans, in each case on the last day of their respective Interest Periods (or, at
the direction of the Borrower, on any earlier date) until all outstanding Term
Loans, AXELs Loans or Acquisition Loans, as the case may be, have been prepaid
or until all the allocable cash on deposit with respect to such Loans has been
exhausted. For purposes of this Agreement, the term "Prepayment Account" shall
mean an account established by the Borrower with the Administrative Agent and
over which the Administrative Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal for application in accordance with
this paragraph (i). The Administrative Agent will, at the request of the
Borrower, invest amounts on deposit in the Prepayment Account in Permitted
Investments that mature prior to the last day of the applicable Interest Periods
of the Eurodollar Term Borrowings, Eurodollar AXELs Borrowings or Eurodollar
Acquisition Borrowings to be prepaid, as the case may be; provided, however,
that (i) the Administrative Agent shall not be required to make any investment
that, in its sole judgment, would require or cause the Administrative Agent to
be in, or would result in any, violation of any law, statute, rule or regulation
and (ii) the Administrative Agent shall have no obligation to invest amounts on
deposit in the Prepayment Account if a Default or Event of Default shall have
occurred and be continuing. The Borrower shall indemnify the Administrative
Agent for any losses relating to the investments so that the amount available to
prepay Eurodollar Borrowings on the last day of the applicable Interest Period
is not less than the amount that would have been available had no investments
been made pursuant thereto. Other than any interest earned on such investments,
the Prepayment Account shall not bear interest. Interest or profits, if any, on
such investments shall be deposited in the Prepayment Account and reinvested and
disbursed as specified above. If the maturity of the Loans has been accelerated
pursuant to Article VII, the Administrative Agent may, in its sole discretion,
apply all amounts on deposit in the Prepayment Account to satisfy any of the
Obligations. The Borrower hereby grants to the Administrative Agent, for its
benefit and the benefit of the Issuing Bank, the Swingline Lender and the
Lenders, a security interest in the Prepayment Account to secure the
Obligations.

                                                                              46





         (j) Any AXELs Lender may elect, by notice to the Administrative Agent
in writing (or by telephone or telecopy promptly confirmed in writing) at least
one Business Day prior to any prepayment of AXELs Loans required to be made by
the Borrower for the account of such Lender pursuant to this Section 2.13, other
than mandatory prepayments required pursuant to Section 2.13(b), to cause all or
a portion of such prepayment to be applied instead to prepay Term Loans and
Acquisition Loans in accordance with paragraph (g) above.

         (k) No prepayments of Acquisition Loans shall be required pursuant to
this Section 2.13 prior to the Acquisition Loan Termination Date (other than
prepayments in connection with a reduction in Revolving Credit Commitments
pursuant to paragraph (l) below). On and after the Acquisition Loan Termination
Date, all prepayments of Acquisition Loans pursuant to this Section 2.13 shall
automatically and permanently reduce the Total Revolving Credit Commitment by
the amount of such prepayment.

         (l) In the event that, upon the occurrence of any event described in
Section 2.13(b), (c), (d), (e) or (f), no Term Loans, AXELs Loans or Acquisition
Loans are outstanding that are required to be prepaid pursuant to Section
2.13(b), (c), (d), (e), (f) or (k) the Borrower shall reduce the Revolving
Credit Commitments in accordance with paragraph (a) above by the amount of the
applicable Net Cash Proceeds, Extraordinary Amounts or Excess Cash Flow, as the
case may be.

         SECTION 2.14. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision of this Agreement, if after the date of this
Agreement any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender or the Issuing
Bank of the principal of or interest on any Eurodollar Loan made by such Lender
or any Fees or other amounts payable hereunder (other than changes in respect of
taxes imposed on the overall net income of such Lender or the Issuing Bank by
the jurisdiction in which such Lender or the Issuing Bank has its principal
office or by any political subdivision or taxing authority therein), or shall
impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of or credit
extended by any Lender or the Issuing Bank (except any such reserve requirement
which is reflected in the Adjusted LIBO Rate) or shall impose on such Lender or
the Issuing Bank or the London interbank market any other condition affecting
this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit
or participation therein, and the result of any of the foregoing shall be to
increase the cost to such Lender or the Issuing Bank of making or maintaining
any Eurodollar Loan or increase the cost to any Lender of issuing or maintaining
any Letter of Credit or purchasing or maintaining a participation therein or to
reduce the amount of any sum received or receivable by such Lender or the
Issuing Bank hereunder (whether of principal, interest or otherwise) by an
amount deemed by such Lender or the Issuing Bank to be material, then the
Borrower will pay to such Lender or the Issuing Bank, as the case may be, upon
demand such additional amount or amounts as will compensate such Lender or the
Issuing Bank, as the case may be, for such additional costs incurred or
reduction suffered.

         (b) If any Lender or the Issuing Bank shall have determined that the
adoption after the date hereof of any law, rule, regulation, agreement or
guideline regarding capital adequacy, or
<PAGE>   53
                                                                              47





any change after the date hereof in any such law, rule, regulation, agreement or
guideline (whether such law, rule, regulation, agreement or guideline has been
adopted) or in the interpretation or administration thereof by any Governmental
Authority charged with the interpretation or administration thereof, or
compliance by any Lender (or any lending office of such Lender) or the Issuing
Bank or any Lender's or the Issuing Bank's holding company with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any Governmental Authority has or would have the effect of reducing the rate of
return on such Lender's or the Issuing Bank's capital or on the capital of such
Lender's or the Issuing Bank's holding company, if any, as a consequence of this
Agreement or the Loans made or participations in Letters of Credit purchased by
such Lender pursuant hereto or the Letters of Credit issued by the Issuing Bank
pursuant hereto to a level below that which such Lender or the Issuing Bank or
such Lender's or the Issuing Bank's holding company would have achieved but for
such applicability, adoption, change or compliance (taking into consideration
such Lender's or the Issuing Bank's policies and the policies of such Lender's
or the Issuing Bank's holding company with respect to capital adequacy) by an
amount deemed by such Lender or the Issuing Bank to be material, then from time
to time the Borrower shall pay to such Lender or the Issuing Bank, as the case
may be, such additional amount or amounts as will compensate such Lender or the
Issuing Bank or such Lender's or the Issuing Bank's holding company for any such
reduction suffered.

         (c) A certificate of a Lender or the Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or the Issuing Bank or its
holding company, as applicable, as specified in paragraph (a) or (b) above shall
be delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay such Lender or the Issuing Bank the amount shown as due on
any such certificate delivered by it within 10 days after its receipt of the
same.

         (d) Failure or delay on the part of any Lender or the Issuing Bank to
demand compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital shall not constitute a waiver of
such Lender's or the Issuing Bank's right to demand such compensation. The
protection of this Section shall be available to each Lender and the Issuing
Bank regardless of any possible contention of the invalidity or inapplicability
of the law, rule, regulation, agreement, guideline or other change or condition
that shall have occurred or been imposed.

         SECTION 2.15. Change in Legality. (a) Notwithstanding any other
provision of this Agreement, if, after the date hereof, any change in any law or
regulation or in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall make it unlawful
for any Lender to make or maintain any Eurodollar Loan or to give effect to its
obligations as contemplated hereby with respect to any Eurodollar Loan, then, by
written notice to the Borrower and to the Administrative Agent:

                  (i) such Lender may declare that Eurodollar Loans will not
         thereafter (for the duration of such unlawfulness) be made by such
         Lender hereunder (or be continued for additional Interest Periods and
         Base Rate Loans will not thereafter (for such duration) be converted
         into Eurodollar Loans), whereupon any request for a Eurodollar
         Borrowing (or to convert a Base Rate Borrowing to a Eurodollar
         Borrowing or to continue a Eurodollar
<PAGE>   54
                                                                              48





         Borrowing for an additional Interest Period) shall, as to such Lender
         only, be deemed a request for a Base Rate Loan (or a request to
         continue a Base Rate Loan as such for an additional Interest Period or
         to convert a Eurodollar Loan into a Base Rate Loan, as the case may
         be), unless such declaration shall be subsequently withdrawn; and

                 (ii) such Lender may require that all outstanding Eurodollar
         Loans made by it be converted to Base Rate Loans, in which event all
         such Eurodollar Loans shall be automatically converted to Base Rate
         Loans as of the effective date of such notice as provided in paragraph
         (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal that would otherwise have been applied to
repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
Base Rate Loans made by such Lender in lieu of, or resulting from the conversion
of, such Eurodollar Loans.

         (b) For purposes of this Section 2.15, a notice to the Borrower by any
Lender shall be effective as to each Eurodollar Loan made by such Lender, if
lawful, on the last day of the Interest Period currently applicable to such
Eurodollar Loan; in all other cases such notice shall be effective on the date
of receipt by the Borrower.

         SECTION 2.16. Indemnity. The Borrower shall indemnify each Lender
against any loss or expense that such Lender may sustain or incur as a
consequence of (a) any event, other than a default by such Lender in the
performance of its obligations hereunder, which results in (i) such Lender
receiving or being deemed to receive any amount on account of the principal of
any Eurodollar Loan prior to the end of the Interest Period in effect therefor,
(ii) the conversion of any Eurodollar Loan to a Base Rate Loan, or the
conversion of the Interest Period with respect to any Eurodollar Loan, in each
case other than on the last day of the Interest Period in effect therefor, or
(iii) any Eurodollar Loan to be made by such Lender (including any Eurodollar
Loan to be made pursuant to a conversion or continuation under Section 2.10) not
being made after notice of such Loan shall have been given by the Borrower
hereunder (any of the events referred to in this clause (a) being called a
"Breakage Event") or (b) any default in the making of any payment or prepayment
required to be made hereunder. In the case of any Breakage Event, such loss
shall include an amount equal to the excess, as reasonably determined by such
Lender, of (i) its cost of obtaining funds for the Eurodollar Loan that is the
subject of such Breakage Event for the period from the date of such Breakage
Event to the last day of the Interest Period in effect (or that would have been
in effect) for such Loan over (ii) the amount of interest likely to be realized
by such Lender in redeploying the funds released or not utilized by reason of
such Breakage Event for such period. A certificate of any Lender setting forth
any amount or amounts which such Lender is entitled to receive pursuant to this
Section 2.16 shall be delivered to the Borrower and shall be conclusive absent
manifest error.

         SECTION 2.17. Pro Rata Treatment. Except as provided below in this
Section 2.17 with respect to Swingline Loans and as required under Sections
2.13(j) and 2.15, each Borrowing, each payment or prepayment of principal of any
Borrowing, each payment of interest on the Loans, each payment of the Commitment
Fees, each reduction of the Term Loan Commitments, AXELs Commitments or the
Revolving Credit Commitments and each conversion of any
<PAGE>   55
                                                                              49





Borrowing to or continuation of any Borrowing as a Borrowing of any Type shall
be allocated pro rata among the Lenders in accordance with their respective
applicable Commitments (or, if such Commitments shall have expired or been
terminated, in accordance with the respective principal amounts of their
outstanding Loans). For purposes of determining the available Revolving Credit
Commitments of the Lenders at any time, each outstanding Swingline Loan shall be
deemed to have utilized the Revolving Credit Commitments of the Lenders
(including those Lenders which shall not have made Swingline Loans) pro rata in
accordance with such respective Revolving Credit Commitments. Each Lender agrees
that in computing such Lender's portion of any Borrowing to be made hereunder,
the Administrative Agent may, in its discretion, round each Lender's percentage
of such Borrowing to the next higher or lower whole dollar amount.

         SECTION 2.18. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim against
the Borrower or any other Loan Party, or pursuant to a secured claim under
Section 506 of Title 11 of the United States Code or other security or interest
arising from, or in lieu of, such secured claim, received by such Lender under
any applicable bankruptcy, insolvency or other similar law or otherwise, or by
any other means, obtain payment (voluntary or involuntary) in respect of any
Loan or Loans or L/C Disbursement as a result of which the unpaid principal
portion of its Term Loans, AXELs Loans and Revolving Loans and participations in
L/C Disbursements shall be proportionately less than the unpaid principal
portion of the Term Loans, AXELs Loans and Revolving Loans and participations in
L/C Disbursements of any other Lender, it shall be deemed simultaneously to have
purchased from such other Lender at face value, and shall promptly pay to such
other Lender the purchase price for, a participation in the Term Loans, AXELs
Loans and Revolving Loans and L/C Exposure, as the case may be of such other
Lender, so that the aggregate unpaid principal amount of the Term Loans, AXELs
Loans and Revolving Loans and L/C Exposure and participations in Term Loans,
AXELs Loans and Revolving Loans and L/C Exposure held by each Lender shall be in
the same proportion to the aggregate unpaid principal amount of all Term Loans,
AXELs Loans and Revolving Loans and L/C Exposure then outstanding as the
principal amount of its Term Loans, AXELs Loans and Revolving Loans and L/C
Exposure prior to such exercise of banker's lien, setoff or counterclaim or
other event was to the principal amount of all Term Loans, AXELs Loans and
Revolving Loans and L/C Exposure outstanding prior to such exercise of banker's
lien, setoff or counterclaim or other event; provided, however, that if any such
purchase or purchases or adjustments shall be made pursuant to this Section 2.18
and the payment giving rise thereto shall thereafter be recovered, such purchase
or purchases or adjustments shall be rescinded to the extent of such recovery
and the purchase price or prices or adjustment restored without interest. The
Borrower and Allied expressly consent to the foregoing arrangements and agree
that any Lender holding a participation in a Term Loan, AXELs Loan or Revolving
Loan or L/C Disbursement deemed to have been so purchased may exercise any and
all rights of banker's lien, setoff or counterclaim with respect to any and all
moneys owing by the Borrower and Allied to such Lender by reason thereof as
fully as if such Lender had made a Loan directly to the Borrower in the amount
of such participation.

         SECTION 2.19. Payments. (a) The Borrower shall make each payment
(including principal of or interest on any Borrowing or any L/C Disbursement or
any Fees or other amounts) hereunder and under any other Loan Document not later
than 12:00 (noon), New York City time, on the date when due in immediately
available dollars, without setoff, defense or
<PAGE>   56
                                                                              50





counterclaim. Each such payment (other than (i) Issuing Bank Fees, which shall
be paid directly to the Issuing Bank, and (ii) principal of and interest on
Swingline Loans, which shall be paid directly to the Swingline Lender except as
otherwise provided in Section 2.22(e)) shall be made to the Administrative Agent
at its offices at 11 Madison Avenue, New York, New York.

         (b) Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of
interest or Fees, if applicable.

         SECTION 2.20. Taxes. (a) Any and all payments by or on behalf of the
Borrower or any Loan Party hereunder and under any other Loan Document shall be
made, in accordance with Section 2.19, free and clear of and without deduction
for any and all current or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding (i) income
taxes imposed on the net income of the Administrative Agent, the Syndication
Agent, the Documentation Agent, any Lender or the Issuing Bank (or any
transferee or assignee thereof, including a participation holder (any such
entity a "Transferee")) and (ii) franchise taxes imposed on the net income of
the Administrative Agent, the Syndication Agent, the Documentation Agent, any
Lender or the Issuing Bank (or Transferee), in each case by the jurisdiction
under the laws of which the Administrative Agent, the Syndication Agent, the
Documentation Agent, such Lender or the Issuing Bank (or Transferee) is
organized or in which the principal office or applicable lending office of the
Administrative Agent, the Syndication Agent, the Documentation Agent, such
Lender or the Issuing Bank (or Transferee) is located or any political
subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities, collectively or individually, being
called "Taxes"). If the Borrower or any Loan Party shall be required to deduct
any Taxes from or in respect of any sum payable hereunder or under any other
Loan Document to the Administrative Agent, the Syndication Agent, the
Documentation Agent, any Lender or the Issuing Bank (or any Transferee), (i) the
sum payable shall be increased by the amount (an "additional amount") necessary
so that after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.20) the Administrative Agent, the
Syndication Agent, the Documentation Agent, such Lender or the Issuing Bank (or
Transferee), as the case may be, shall receive an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower or such
Loan Party shall make such deductions and (iii) the Borrower or such Loan Party
shall pay the full amount deducted to the relevant Governmental Authority in
accordance with applicable law.

         (b) In addition, the Borrower agrees to pay to the relevant
Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies (including, without limitation, mortgage recording taxes and
similar fees) that arise from any payment made hereunder or under any other Loan
Document or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement or any other Loan Document ("Other Taxes").

         (c) The Borrower will indemnify the Administrative Agent, the
Syndication Agent, the Documentation Agent, each Lender and the Issuing Bank (or
Transferee) for the full amount of
<PAGE>   57
                                                                              51





Taxes and Other Taxes paid by the Administrative Agent, such Lender or the
Issuing Bank (or Transferee), as the case may be, and any liability (including
penalties, interest and expenses (including reasonable attorney's fees and
expenses)) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted by the relevant Governmental
Authority (it being understood that such indemnification shall not impair any
right that the Borrower may have to contest with the relevant Governmental
Authority such Taxes or Other Taxes). A certificate as to the amount of such
payment or liability prepared by the Administrative Agent, the Syndication
Agent, the Documentation Agent, a Lender or the Issuing Bank (or Transferee), or
the Administrative Agent on its behalf, absent manifest error, shall be final,
conclusive and binding for all purposes. Such indemnification shall be made
within 30 days after the date the Administrative Agent, any Lender, the
Syndication Agent, the Documentation Agent, or the Issuing Bank (or Transferee),
as the case may be, makes written demand therefor.


         (d) As soon as practicable after the date of any payment of Taxes or
Other Taxes by the Borrower or any other Loan Party to the relevant Governmental
Authority, the Borrower or such other Loan Party will deliver to the
Administrative Agent, at its address referred to in Section 9.01, the original
or a certified copy of a receipt issued by such Governmental Authority
evidencing payment thereof.

         (e) Each Lender (or Transferee) that is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") shall deliver to the Borrower and the
Administrative Agent two copies of either United States Internal Revenue Service
Form 1001 or Form 4224, or, in the case of a Non-U.S. Lender claiming exemption
from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Non-U.S. Lender delivers a
Form W-8, a certificate representing that such Non-U.S. Lender is not a bank for
purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within
the meaning of Section 871(h)(3)(B) of the Code) of the Borrower and is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Code)), properly completed and duly executed by such
Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S.
Federal withholding tax on payments by the Borrower under this Agreement and the
other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on
or before the date it becomes a party to this Agreement (or, in the case of a
Transferee that is a participation holder, on or before the date such
participation holder becomes a Transferee hereunder) and on or before the date,
if any, such Non-U.S. Lender changes its applicable lending office by
designating a different lending office (a "New Lending Office"). In addition,
each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S. Lender.
Notwithstanding any other provision of this Section 2.20(e), a Non-U.S. Lender
shall not be required to deliver any form pursuant to this Section 2.20(e) that
such Non-U.S. Lender is not legally able to deliver.

         (f) The Borrower shall not be required to indemnify any Non-U.S. Lender
or to pay any additional amounts to any Non-U.S. Lender, in respect of United
States Federal withholding tax pursuant to paragraph (a) or (c) above to the
extent that (i) the obligation to withhold amounts with respect to United States
Federal withholding tax existed on the date such Non-U.S. Lender
<PAGE>   58
                                                                              52





became a party to this Agreement (or, in the case of a Transferee that is a
participation holder, on the date such participation holder became a Transferee
hereunder) or, with respect to payments to a New Lending Office, the date such
Non-U.S. Lender designated such New Lending Office with respect to a Loan;
provided, however, that this paragraph (f) shall not apply (x) to any Transferee
or New Lending Office that becomes a Transferee or New Lending Office as a
result of an assignment, participation, transfer or designation made at the
request of the Borrower and (y) to the extent the indemnity payment or
additional amounts any Transferee, or any Lender (or Transferee), acting through
a New Lending Office, would be entitled to receive (without regard to this
paragraph (f)) do not exceed the indemnity payment or additional amounts that
the person making the assignment, participation or transfer to such Transferee,
or Lender (or Transferee) making the designation of such New Lending Office,
would have been entitled to receive in the absence of such assignment,
participation, transfer or designation or (ii) the obligation to pay such
additional amounts would not have arisen but for a failure by such Non-U.S.
Lender to comply with the provisions of paragraph (e) above.

         (g) Nothing contained in this Section 2.20 shall require any Lender or
the Issuing Bank (or any Transferee) or the Administrative Agent, the
Syndication Agent or the Documentation Agent to make available any of its tax
returns (or any other information that it deems to be confidential or
proprietary).

         SECTION 2.21. Assignment of Commitments Under Certain Circumstances;
Duty to Mitigate. (a) In the event (i) any Lender or the Issuing Bank delivers a
certificate requesting compensation pursuant to Section 2.14, (ii) any Lender or
the Issuing Bank delivers a notice described in Section 2.15 or (iii) the
Borrower is required to pay any additional amount to any Lender or the Issuing
Bank or any Governmental Authority on account of any Lender or the Issuing Bank
pursuant to Section 2.20, the Borrower may, at its sole expense and effort
(including with respect to the processing and recordation fee referred to in
Section 9.04(b)), upon notice to such Lender or the Issuing Bank and the
Administrative Agent, require such Lender or the Issuing Bank to transfer and
assign, without recourse (in accordance with and subject to the restrictions
contained in Section 9.04), all of its interests, rights and obligations under
this Agreement to an assignee that shall assume such assigned obligations (which
assignee may be another Lender, if a Lender accepts such assignment); provided
that (x) such assignment shall not conflict with any law, rule or regulation or
order of any court or other Governmental Authority having jurisdiction, (y) the
Borrower shall have received the prior written consent of the Administrative
Agent (and, if a Revolving Credit Commitment is being assigned, of the Issuing
Bank and the Swingline Lender), which consent shall not unreasonably be
withheld, and (z) the Borrower or such assignee shall have paid to the affected
Lender or the Issuing Bank in immediately available funds an amount equal to the
sum of the principal of and interest accrued to the date of such payment on the
outstanding Loans or L/C Disbursements of such Lender or the Issuing Bank,
respectively, plus all Fees and other amounts accrued for the account of such
Lender or the Issuing Bank hereunder (including any amounts under Section 2.14
and Section 2.16); provided further that, if prior to the giving of such notice
the circumstances or event that resulted in such Lender's or the Issuing Bank's
claim for compensation under Section 2.14 or notice under Section 2.15 or the
amounts paid pursuant to Section 2.20, as the case may be, cease to cause such
Lender or the Issuing Bank to suffer increased costs or reductions in amounts
received or receivable or reduction in return on capital, or cease to have the
consequences specified in Section 2.15, or cease to result in amounts being
payable under
<PAGE>   59
                                                                              53





Section 2.20, as the case may be (including as a result of any action taken by
such Lender or the Issuing Bank pursuant to paragraph (b) below), or if such
Lender or the Issuing Bank shall waive its right to claim further compensation
under Section 2.14 in respect of such circumstances or event or shall withdraw
its notice under Section 2.15 or shall waive its right to further payments under
Section 2.20 in respect of such circumstances or event, as the case may be, then
such Lender or the Issuing Bank shall not thereafter be required to make any
such transfer and assignment hereunder.

         (b) If (i) any Lender or the Issuing Bank shall request compensation
under Section 2.14, (ii) any Lender or the Issuing Bank delivers a notice
described in Section 2.15 or (iii) the Borrower is required to pay any
additional amount to any Lender or the Issuing Bank or any Governmental
Authority on account of any Lender or the Issuing Bank, pursuant to Section
2.20, then such Lender or the Issuing Bank shall use reasonable efforts (which
shall not require such Lender or the Issuing Bank to incur an unreimbursed loss
or unreimbursed cost or expense or otherwise take any action inconsistent with
its internal policies or legal or regulatory restrictions or suffer any
disadvantage or burden deemed by it to be significant) (x) to file any
certificate or document reasonably requested in writing by the Borrower or (y)
to assign its rights and delegate and transfer its obligations hereunder to
another of its offices, branches or affiliates, if such filing or assignment
would reduce its claims for compensation under Section 2.14 or enable it to
withdraw its notice pursuant to Section 2.15 or would reduce amounts payable
pursuant to Section 2.20, as the case may be, in the future. The Borrower hereby
agrees to pay all reasonable costs and expenses incurred by any Lender or the
Issuing Bank in connection with any such filing or assignment, delegation and
transfer.

         SECTION 2.22. Swingline Loans. (a) Swingline Commitment. Subject to the
terms and conditions and relying upon the representations and warranties herein
set forth, the Swingline Lender agrees to make loans to the Borrower at any time
and from time to time on and after the Closing Date and until the earlier of the
Revolving Credit Maturity Date and the termination of the Revolving Credit
Commitments in accordance with the terms hereof, in an aggregate principal
amount at any time outstanding that will not result in (i) the aggregate
principal amount of all Swingline Loans exceeding $20,000,000 in the aggregate
or (ii) the Aggregate Revolving Credit Exposure, after giving effect to any
Swingline Loan, exceeding the Total Revolving Credit Commitment. Each Swingline
Loan shall be in a minimum principal amount of $1,000,000 that is an integral
multiple of $250,000. The Swingline Commitment may be terminated or reduced from
time to time as provided herein. Within the foregoing limits, the Borrower may
borrow, pay or prepay and reborrow Swingline Loans hereunder, subject to the
terms, conditions and limitations set forth herein.

         (b) Swingline Loans. The Borrower shall notify the Administrative Agent
by telecopy, or by telephone (confirmed by telecopy), not later than 10:00 a.m.,
New York City time, on the day of a proposed Swingline Loan. Such notice shall
be delivered on a Business Day, shall be irrevocable and shall refer to this
Agreement and shall specify the requested date (which shall be a Business Day)
and amount of such Swingline Loan. The Administrative Agent will promptly advise
the Swingline Lender of any notice received from the Borrower pursuant to this
paragraph (b). The Swingline Lender shall make each Swingline Loan available to
the Borrower by means of a credit to an account in the name of the Borrower
designated by the Borrower by 3:00 p.m. on the date such Swingline Loan is so
requested.
<PAGE>   60
                                                                              54





         (c) Prepayment. The Borrower shall have the right at any time and from
time to time to prepay any Swingline Loan, in whole or in part, upon giving
written or telecopy notice (or telephone notice promptly confirmed by written,
or telecopy notice) to the Swingline Lender and to the Administrative Agent
before 12:00 (noon), New York City time on the date of prepayment at the
Swingline Lender's address for notices specified on Schedule 2.01. All principal
payments of Swingline Loans shall be accompanied by accrued interest on the
principal amount being repaid to the date of payment.

         (d) Interest. Each Swingline Loan shall be a Base Rate Loan and,
subject to the provisions of Section 2.07, shall bear interest as provided in
Section 2.06(a).

         (e) Participations. The Swingline Lender may by written notice given to
the Administrative Agent not later than 10:00 a.m., New York City time, on any
Business Day require the Revolving Credit Lenders to acquire participations on
such Business Day in all or a portion of the Swingline Loans outstanding. Such
notice shall specify the aggregate amount of Swingline Loans in which Revolving
Credit Lenders will participate. The Administrative Agent will, promptly upon
receipt of such notice, give notice to each Revolving Credit Lender, specifying
in such notice such Lender's Pro Rata Percentage of such Swingline Loan or
Loans. In furtherance of the foregoing, each Revolving Credit Lender hereby
absolutely and unconditionally agrees, upon receipt of notice as provided above,
to pay to the Administrative Agent, for the account of the Swingline Lender,
such Revolving Credit Lender's Pro Rata Percentage of such Swingline Loan or
Loans. Each Revolving Credit Lender acknowledges and agrees that its obligation
to acquire participations in Swingline Loans pursuant to this paragraph is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including the occurrence and continuance of a Default or an Event of
Default, and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever. Each Revolving Credit Lender shall comply
with its obligation under this paragraph by wire transfer of immediately
available funds, in the same manner as provided in Section 2.02(c) with respect
to Loans made by such Lender (and Section 2.02(c) shall apply, mutatis mutandis,
to the payment obligations of the Lenders) and the Administrative Agent shall
promptly pay to the Swingline Lender the amounts so received by it from the
Lenders. The Administrative Agent shall notify the Borrower of any
participations in any Swingline Loan acquired pursuant to this paragraph and
thereafter payments in respect of such Swingline Loan shall be made to the
Administrative Agent and not to the Swingline Lender. Any amounts received by
the Swingline Lender from the Borrower (or other party on behalf of the
Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender
of the proceeds of a sale of participations therein shall be promptly remitted
to the Administrative Agent; any such amounts received by the Administrative
Agent shall be promptly remitted by the Administrative Agent to the Lenders that
shall have made their payments pursuant to this paragraph and to the Swingline
Lender, as their interests may appear. The purchase of participations in a
Swingline Loan pursuant to this paragraph shall not relieve the Borrower (or
other party liable for obligations of the Borrower) of any default in the
payment thereof.

         SECTION 2.23. Letters of Credit. (a) General. The Borrower may request
the issuance of a Letter of Credit for its own account or the account of any
other Account Party (provided that the Borrower shall be a co-applicant and
co-obligor with respect to each Letter of Credit issued for the account of any
other Account Party), in a form reasonably acceptable to the
<PAGE>   61
                                                                              55





Administrative Agent and the Issuing Bank, at any time and from time to time
while the Revolving Credit Commitments remain in effect. This Section shall not
be construed to impose an obligation upon the Issuing Bank to issue any Letter
of Credit that is inconsistent with the terms and conditions of this Agreement.

         (b) Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions. In order to request the issuance of a Letter of Credit (or to amend,
renew or extend an existing Letter of Credit), the Borrower shall hand deliver
or telecopy to the Issuing Bank and the Administrative Agent (reasonably in
advance of the requested date of issuance, amendment, renewal or extension) a
notice requesting the issuance of a Letter of Credit, or identifying the Letter
of Credit to be amended, renewed or extended, the date of issuance, amendment,
renewal or extension, the date on which such Letter of Credit is to expire
(which shall comply with paragraph (c) below), the amount of such Letter of
Credit, the name and address of the beneficiary thereof and such other
information as shall be necessary to prepare such Letter of Credit. Following
receipt of such notice and prior to the issuance of the requested Letter of
Credit or the applicable amendment, renewal or extension, the Administrative
Agent shall notify the Issuing Bank of the amount of the Aggregate Revolving
Credit Exposure after giving effect to (i) the issuance, amendment, renewal or
extension of such Letter of Credit, (ii) the issuance or expiration of any other
Letter of Credit that is to be issued or will expire prior to the requested date
of issuance of such Letter of Credit and (iii) the borrowing or repayment of any
Revolving Credit Loans or Swingline Loans that (based upon notices delivered to
the Administrative Agent by the Borrower) are to be borrowed or repaid prior to
the requested date of issuance of such Letter of Credit. A Letter of Credit
shall be issued, amended, renewed or extended only if, and upon issuance,
amendment, renewal or extension of each Letter of Credit the Borrower shall be
deemed to represent and warrant that, after giving effect to such issuance,
amendment, renewal or extension (A) the L/C Exposure shall not exceed
$150,000,000 and (B) the Aggregate Revolving Credit Exposure shall not exceed
the Total Revolving Credit Commitment.

         (c) Expiration Date. Each Letter of Credit shall expire at the close of
business on the date one year after the date of the issuance of such Letter of
Credit (other than any Back-up Letter of Credit, which shall expire on the
expiry date of the letter of credit that such Back-up Letter of Credit supports,
as set forth on Schedule 1.01(a)), unless such Letter of Credit expires by its
terms on an earlier date; provided, however, that each Letter of Credit may,
upon the request of the Borrower, include a provision whereby such Letter of
Credit shall be renewed automatically for additional consecutive periods 12
months or less unless the Issuing Bank notifies the beneficiary thereof not more
than 45, nor fewer than 30, days prior to the then applicable expiry date (or
such other notification periods as set forth in the Back-up Letters of Credit as
set forth on Schedule 1.01(a)) that such Letter of Credit will not be renewed;
provided further, however, that no Letter of Credit may expire or be extended
beyond the date that is five Business Days prior to the Revolving Credit
Maturity Date unless, on or prior to the date such Letter of Credit is issued or
extended, the Borrower shall have deposited with the Collateral Agent an amount
equal to 110% of the face amount of such Letter of Credit in a cash collateral
account established with the Collateral Agent for the benefit of the Secured
Parties.

         (d) Participations. By the issuance of a Letter of Credit and without
any further action on the part of the Issuing Bank or the Lenders, the Issuing
Bank hereby grants to each Revolving Credit Lender, and each such Lender hereby
acquires from the applicable Issuing Bank, a
<PAGE>   62
                                                                              56





participation in such Letter of Credit equal to such Lender's Pro Rata
Percentage of the aggregate amount available to be drawn under such Letter of
Credit, effective upon the issuance of such Letter of Credit. In addition, the
Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from
the Issuing Bank, a participation in each Existing Letter of Credit equal to
such Lender's Pro Rata Percentage of the face amount of such Existing Letter of
Credit, effective on the Closing Date. In consideration and in furtherance of
the foregoing, each Revolving Credit Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of
the Issuing Bank, such Lender's Pro Rata Percentage of each L/C Disbursement
made by the Issuing Bank and not reimbursed by the applicable Account Party (or,
if applicable, another party pursuant to its obligations under any other Loan
Document) forthwith on the date due as provided in Section 2.02(f). Each
Revolving Credit Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this paragraph in respect of Letters of Credit is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including the occurrence and continuance of a Default or an Event of
Default, and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever.

         (e) Reimbursement. If the Issuing Bank shall make any L/C Disbursement
in respect of a Letter of Credit, the applicable Account Party shall pay to the
Administrative Agent an amount equal to such L/C Disbursement not later than two
hours after such Account Party shall have received notice from the Issuing Bank
that payment of such draft will be made, or, if such Account Party shall have
received such notice later than 10:00 a.m., New York City time, on any Business
Day, not later than 10:00 a.m., New York City time, on the immediately following
Business Day.

         (f) Obligations Absolute. Each Account Party's obligations to reimburse
L/C Disbursements as provided in paragraph (e) above shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement, under any and all circumstances whatsoever,
and irrespective of:

                  (i) any lack of validity or enforceability of any Letter of
         Credit or any Loan Document, or any term or provision therein;

                  (ii) any amendment or waiver of or any consent to departure
         from all or any of the provisions of any Letter of Credit or any Loan
         Document;

                  (iii) the existence of any claim, setoff, defense or other
         right that the Account Party, any other party guaranteeing, or
         otherwise obligated with, the Account Party, any Subsidiary or other
         Affiliate thereof or any other person may at any time have against the
         beneficiary under any Letter of Credit, the Issuing Bank, the
         Administrative Agent or any Lender or any other person, whether in
         connection with this Agreement, any other Loan Document or any other
         related or unrelated agreement or transaction;

                  (iv) any draft or other document presented under a Letter of
         Credit proving to be forged, fraudulent, invalid or insufficient in any
         respect or any statement therein being untrue or inaccurate in any
         respect;
<PAGE>   63
                                                                              57





                  (v) payment by the Issuing Bank under a Letter of Credit
         against presentation of a draft or other document that does not comply
         with the terms of such Letter of Credit; and

                 (vi) any other act or omission to act or delay of any kind of
         the Issuing Bank, the Lenders, the Administrative Agent or any other
         person or any other event or circumstance whatsoever (other than
         payment against presentation of drafts or documents that, as a result
         of the Issuing Bank's negligence, do not comply with the terms of such
         Letter of Credit), whether or not similar to any of the foregoing, that
         might, but for the provisions of this Section, constitute a legal or
         equitable discharge of the Account Party's obligations hereunder.

         Without limiting the generality of the foregoing, it is expressly
understood and agreed that the absolute and unconditional obligation of each
Account Party hereunder to reimburse L/C Disbursements will not be excused by
the gross negligence or wilful misconduct of the Issuing Bank. However, the
foregoing shall not be construed to excuse the Issuing Bank from liability to
such Account Party to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the
Borrower, Allied and the other Account Parties to the extent permitted by
applicable law) suffered by such Account Party that are caused by the Issuing
Bank's gross negligence or wilful misconduct in determining whether drafts and
other documents presented under a Letter of Credit comply with the terms
thereof; it is understood that the Issuing Bank may accept documents that appear
on their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary and, in making any
payment under any Letter of Credit (i) the Issuing Bank's exclusive reliance on
the documents presented to it under such Letter of Credit as to any and all
matters set forth therein, including reliance on the amount of any draft
presented under such Letter of Credit, whether or not the amount due to the
beneficiary thereunder equals the amount of such draft and whether or not any
document presented pursuant to such Letter of Credit proves to be insufficient
in any respect, if such document on its face appears to be in order, and whether
or not any other statement or any other document presented pursuant to such
Letter of Credit proves to be forged or invalid or any statement therein proves
to be inaccurate or untrue in any respect whatsoever and (ii) any noncompliance
in any immaterial respect of the documents presented under such Letter of Credit
with the terms thereof shall, in each case, be deemed not to constitute wilful
misconduct or gross negligence of the Issuing Bank.

         (g) Disbursement Procedures. The Issuing Bank shall, promptly following
its receipt thereof, examine all documents purporting to represent a demand for
payment under a Letter of Credit. The Issuing Bank shall as promptly as possible
give telephonic notification, confirmed by telecopy, to the Administrative Agent
and the applicable Account Party of such demand for payment and whether the
Issuing Bank has made or will make an L/C Disbursement thereunder; provided that
any failure to give or delay in giving such notice shall not relieve the Account
Party of its obligation to reimburse the Issuing Bank and the Revolving Credit
Lenders with respect to any such L/C Disbursement. The Administrative Agent
shall promptly give each Revolving Credit Lender notice thereof.

         (h) Interim Interest. If the Issuing Bank shall make any L/C
Disbursement in respect of a Letter of Credit, then, unless the applicable
Account Party shall reimburse such L/C
<PAGE>   64
                                                                              58





Disbursement in full on such date, the unpaid amount thereof shall bear interest
for the account of the Issuing Bank, for each day from and including the date of
such L/C Disbursement, to but excluding the earlier of the date of payment by
the applicable Account Party or the date on which interest shall commence to
accrue thereon as provided in Section 2.02(f), at the rate per annum that would
apply to such amount if such amount were a Base Rate Loan.

         (i) Resignation or Removal of the Issuing Bank. The Issuing Bank may
resign at any time by giving 180 days' prior written notice to the
Administrative Agent, the Lenders and the Borrower, and may be removed at any
time by the Borrower by notice to the Issuing Bank, the Administrative Agent and
the Lenders. Subject to the next succeeding paragraph, upon the acceptance of
any appointment as the Issuing Bank hereunder by a Lender that shall agree to
serve as successor Issuing Bank, such successor shall succeed to and become
vested with all the interests, rights and obligations of the retiring Issuing
Bank and the retiring Issuing Bank shall be discharged from its obligations to
issue additional Letters of Credit hereunder. At the time such removal or
resignation shall become effective, the Borrower shall pay all accrued and
unpaid fees pursuant to Section 2.05(c)(ii). The acceptance of any appointment
as the Issuing Bank hereunder by a successor Lender shall be evidenced by an
agreement entered into by such successor, in a form satisfactory to the Borrower
and the Administrative Agent, and, from and after the effective date of such
agreement, (i) such successor Lender shall have all the rights and obligations
of the previous Issuing Bank under this Agreement and the other Loan Documents
and (ii) references herein and in the other Loan Documents to the term "Issuing
Bank" shall be deemed to refer to such successor or to any previous Issuing
Bank, or to such successor and all previous Issuing Banks, as the context shall
require. After the resignation or removal of the Issuing Bank hereunder, the
retiring Issuing Bank shall remain a party hereto and shall continue to have all
the rights and obligations of an Issuing Bank under this Agreement and the other
Loan Documents with respect to Letters of Credit issued by it prior to such
resignation or removal, but shall not be required to issue additional Letters of
Credit.

         The Administrative Agent may, at the request of the Borrower, appoint a
Lender to issue a specific Letter of Credit under this Agreement in accordance
with the terms hereof, provided that such appointment shall only be made if the
Borrower can demonstrate that such Letter of Credit may not be issued by the
Issuing Bank or would not otherwise be accepted by the beneficiary of such
Letter of Credit; provided, further, that such appointment shall in no way be
deemed a resignation or removal of the Issuing Bank under this Agreement. Such
appointment shall be subject to the consent of the applicable Lender. Unless the
context otherwise requires, references herein and in the other Loan Documents to
the term Issuing Bank shall refer to the Issuing Bank hereunder and such Lender
appointed by the Administrative Agent to issue a Letter of Credit.

         (j) Cash Collateralization. If any Event of Default shall occur and be
continuing, or if the Total Revolving Credit Commitment is less than the
aggregate L/C Exposure, the Borrower shall, on the Business Day following which
it receives notice from the Administrative Agent or the Required Lenders (or, if
the maturity of the Loans has been accelerated, Revolving Credit Lenders holding
participations in outstanding Letters of Credit representing greater than 50% of
the aggregate undrawn amount of all outstanding Letters of Credit) thereof and
of the amount to be deposited, deposit in an account with the Collateral Agent,
for the benefit of the Revolving Credit Lenders, an amount in cash equal to the
L/C Exposure as of such date. Such deposit shall
<PAGE>   65
                                                                              59





be held by the Collateral Agent as collateral for the payment and performance of
the Obligations. The Collateral Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal, over such account. Other than any
interest earned on the investment of such deposits in Permitted Investments,
which investments shall be made at the option and sole discretion of the
Collateral Agent, such deposits shall not bear interest. Interest or profits, if
any, on such investments shall accumulate in such account. Moneys in such
account shall (i) automatically be applied by the Administrative Agent to
reimburse the Issuing Bank for L/C Disbursements (and all accrued interest
thereon) for which it has not been reimbursed, (ii) be held for the satisfaction
of the reimbursement obligations of the Borrower for the L/C Exposure at such
time and (iii) if the maturity of the Loans has been accelerated (but subject to
the consent of Revolving Credit Lenders holding participations in outstanding
Letters of Credit representing greater than 50% of the aggregate undrawn amount
of all outstanding Letters of Credit), be applied to satisfy the Obligations. If
the Borrower is required to provide an amount of cash collateral hereunder as a
result of the occurrence of an Event of Default, such amount (to the extent not
applied as aforesaid) shall be returned to the Borrower within three Business
Days after all Events of Default have been cured or waived. If the Borrower is
required to provide an amount of cash collateral hereunder pursuant to Section
2.13(a), such amount shall be returned to the Borrower from time to time to the
extent that the amount of such cash collateral held by the Collateral Agent
exceeds the excess, if any, of the aggregate L/C Exposure over the Total
Revolving Credit Commitment; provided, that such return shall not be required at
any time that an Event of Default has occurred and is continuing.

the Borrower or any Subsidiary is a party or by which any of them or any of
their property is or may be bound, (ii) be in conflict with, result in a breach
of or constitute (alone or with notice or lapse of time or both) a default
under, or give rise to any right to accelerate or to require the prepayment,
repurchase or redemption of any obligation under any such indenture, agreement
or other instrument or (iii) result in the creation or imposition of any Lien
upon or with respect to any property or assets now owned or hereafter acquired
by Allied, the Borrower or any Subsidiary (other than any Lien created hereunder
or under the Security Documents).

         SECTION 3.03. Enforceability. This Agreement has been duly executed and
delivered by Allied and the Borrower and constitutes, and each other Loan
Document when executed and delivered by the each Loan Party party thereto will
constitute, a legal, valid and binding obligation of such Loan Party enforceable
against such Loan Party in accordance with its terms.

to the Lenders its consolidated balance sheets and statements of operations,
cash flows and stockholders' equity (i) as of and for each of the three fiscal
years ended December 31, 1995, audited by and accompanied by the opinion of
Arthur Andersen LLP, independent public accountants, and (ii) as of and for the
fiscal quarter and the portion of the fiscal year ended September 30, 1996,
certified by a Financial Officer of Allied. Such financial statements present
fairly in all material respects the financial condition and results of
operations and cash flows of Allied and its consolidated Subsidiaries as of such
dates and for such periods. Such financial statements were prepared in
accordance with GAAP applied on a consistent basis.

         (b) Allied has heretofore delivered to the Lenders its unaudited pro
forma consolidated balance sheet as of September 30, 1996, prepared giving
effect to the Transactions as if they had occurred on such date. Such pro forma
balance sheet has been prepared in good faith by Allied based on the assumptions
used to prepare the pro forma financial information contained in the
Confidential Information Memorandum (which assumptions are believed by Allied on
the date hereof to be reasonable), is based on the best information available to
Allied as of the date of delivery thereof, accurately reflects all material
adjustments required to be made to give effect to the Transactions and presents
fairly on a pro forma basis the estimated consolidated financial position of
Allied as of September 30, 1996, assuming that the Transactions had actually
occurred at September 30, 1996.

assets for their intended purposes. All such material properties and assets are
free and clear of Liens, other than Liens expressly permitted by Section 6.02.

         (b) Each of Allied, the Borrower and the Subsidiaries has complied with
all obligations under all material leases to which it is a party and all such

included therein or delivered pursuant thereto contained, contains or will
contain any material misstatement of fact or omitted, omits or will omit to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were, are or will be made, not misleading;
provided that to the extent any such information, report, financial statement,
exhibit or schedule was based upon or constitutes a forecast, projection or
expressions of opinion, each of Allied and the Borrower represents only that it
acted in good faith and utilized reasonable assumptions and due care in the
preparation of such information, report, financial statement, exhibit or
schedule.

         SECTION 3.16. Employee Benefit Plans. Each of the Borrower and its
ERISA Affiliates is in compliance in all material respects with the applicable
provisions of ERISA and the Code and the regulations and published
interpretations thereunder, except where non-compliance could
<PAGE>   69
                                                                              63





not reasonably be expected to have a Material Adverse Effect. No ERISA Event has
occurred or is reasonably expected to occur that, when taken together with all
other such ERISA Events, could reasonably be expected to result in material

could not reasonably be expected to result in a Material Adverse Effect;

         (c) There have been no Releases or threatened Releases at, from, under
or proximate to the Properties or otherwise in connection with the operations of
the Borrower or the Subsidiaries, which Releases or threatened Releases, in the

expected to result in a Material Adverse Effect, nor do Allied, the Borrower or
the Subsidiaries have reason to believe that any such notice will be received or
is being threatened; and

         (e) Hazardous Materials have not been transported from the Properties,
nor have Hazardous Materials been generated, treated, stored or disposed of at,
on or under any of the Properties in a manner that could give rise to liability

                                                                              64

correct description of all insurance maintained by Allied, the Borrower or by
Allied or the Borrower for its Subsidiaries as of the date hereof and the

result in a Material Adverse Effect. The hours worked by and payments made to
employees of Allied, the Borrower and the Subsidiaries have not been in
violation of the Fair Labor Standards Act or any other applicable Federal,
state, local or foreign law dealing with such matters, which could reasonably be
expected to result in a Material Adverse Effect. All payments due from Allied,
the Borrower or any Subsidiary, or for which any claim may be made against
Allied, the Borrower or any Subsidiary, on account of wages and employee health
and welfare insurance and other benefits, have been paid or accrued as a
liability on the books of Allied, the Borrower or such Subsidiary, except where
the failure to do so could not reasonably be expected to result in a Material
Adverse Effect. The consummation of the Transactions will not give rise to any
right of termination or right of renegotiation on the part of any union under
any collective bargaining agreement to which Allied, the Borrower or any
Subsidiary is bound, except where such event could not reasonably be expected to
result in a Material Adverse Effect.

         SECTION 3.21. Solvency. Immediately after the consummation of the
Transactions to occur on the Closing Date and immediately following the making
of each Loan made on the Closing Date and after giving effect to the application
of the proceeds of such Loans, and taking into account all rights of indemnity,

the Indemnity, Subrogation and Contribution Agreement, (i) the fair value of the
assets of Allied, the Borrower and the other Loan Parties, on a consolidated
basis, at a fair valuation, will exceed its debts and liabilities, subordinated,
contingent or otherwise; (ii) the present fair saleable value of the property of
Allied, the Borrower and the other Loan Parties, on a consolidated basis, will
be greater than the amount that will be required to pay the probable liability
of its debts and other liabilities, subordinated, contingent or otherwise, as
such debts and other liabilities become absolute and matured; (iii) Allied, the
Borrower and the other Loan Parties, on a consolidated basis, will be able to
pay its debts and liabilities, subordinated, contingent or otherwise, as such
debts and liabilities become absolute and matured; and (iv) Allied, the Borrower
and the other Loan Parties, on a consolidated basis, will not have unreasonably
small capital with which to conduct the business in which it is engaged as such
business is now conducted and is proposed to be conducted following the Closing
Date.

insurance carrier shall pay all proceeds otherwise payable to the Borrower or
the Loan Parties under such policies directly to the Collateral Agent; cause all
such policies to provide that neither the Borrower, the Administrative Agent,
the Collateral Agent nor any other party shall be a coinsurer thereunder and to
contain a "Replacement Cost Endorsement", without any deduction for
depreciation, and such other provisions as the Administrative Agent or the
Collateral Agent may reasonably require from time to time to protect their
interests; deliver original or certified copies of all such policies to the
Collateral Agent; cause each such policy to provide that it shall not be
canceled, modified or not renewed (i) by reason of nonpayment of premium upon

Collateral Agent of payment of the premium therefor.

         (c) Notify the Administrative Agent and the Collateral Agent
immediately whenever any separate insurance concurrent in form or contributing
in the event of loss with that required to be maintained under this Section 5.02
is taken out by the Borrower; and promptly deliver to the Administrative Agent

claims for labor, materials and supplies or otherwise that, if unpaid, might
give rise to a Lien upon such properties or any part thereof; provided, however,
that such payment and discharge shall not be required with respect to any such
tax, assessment, charge, levy or claim so long as the validity or amount thereof
shall be contested in good faith by appropriate proceedings and the Borrower
shall have set aside on its books adequate reserves with respect thereto in

contested obligation, tax, assessment or charge and enforcement of a Lien.

renew Environmental Permits or to conduct any Remedial Action could not
reasonably be expected to result in a Material Adverse Effect; provided,
however, that none of Allied, the Borrower or any of the Subsidiaries shall be
required to undertake any Remedial Action to the extent that any applicable
obligation to do so is being contested in good faith and by proper proceedings
and appropriate reserves are being maintained with respect to such
circumstances.

         (b) With respect to any Permitted Acquisition and any acquisition of
any other ownership or leasehold interest in, or the entry into any agreement to

review a favorable written assessment, prepared by an environmental consulting
firm recognized within the municipal solid waste industry and among
environmental professionals as competent and reputable and which the Borrower
has reasonably determined to be suitable, that reasonably addresses the
environmental compliance and liability issues associated with the subject of
such acquisition, agreement or lease (an "Environmental Assessment"); and (ii)
furnish such Environmental Assessment to the Administrative Agent promptly

documents, financing statements, agreements and instruments, and take all
further action (including filing Uniform Commercial Code and other financing
statements, mortgages and deeds of trust) that may be required under applicable
law, or that the Required Lenders, the Administrative Agent, the Syndication
Agent, the Documentation Agent or the Collateral Agent may reasonably request,
in order to effectuate the transactions contemplated by the Loan Documents and
in order to grant, preserve, protect and perfect the validity and first priority
of the security interests created or intended to be created by the Security
Documents. Allied and the Borrower will cause any subsequently acquired or
organized Subsidiary (other than a Subsidiary that conducts no operations, has
total assets not in excess of $5,000 and has no Indebtedness) to execute a
Subsidiary Guarantee Agreement, Indemnity Subrogation and Contribution Agreement
and each applicable Security Document in favor of the Collateral Agent, except
to the extent any such execution by a Foreign Subsidiary would have any adverse
tax consequences for the Borrower or any of the Subsidiaries. In addition, from

or causing to be pledged or created, perfected security interests with respect
to such of its assets and properties (including real property) as the
Administrative Agent or the Required Lenders shall designate (it being
understood that it is the intent of the parties that the Obligations shall be
secured by, among other things, substantially all the assets of Allied and the
Borrower (including real and other properties acquired subsequent to the Closing
Date)). Such security interests and Liens will be created under the Security
Documents and other security agreements, mortgages, deeds of trust and other
instruments and documents in form and substance satisfactory to the Collateral
Agent, and Allied and the Borrower shall deliver or cause to be delivered to the
Collateral Agent all such instruments and documents (including legal opinions,
title insurance policies and lien searches) as the Collateral Agent shall
reasonably request to evidence compliance with this Section. Allied and the
Borrower agree to provide such evidence as the Collateral Agent shall reasonably
request as to the perfection and priority status of each such security interest
and Lien.

and otherwise perform all obligations in respect of all leases of real property
to which Allied, the Borrower or any of the Subsidiaries is a party, keep such
leases in full force and effect and not allow such leases to lapse or be
terminated or any rights to renew such leases to be forfeited or cancelled,
notify the Administrative Agent of any default by any party with respect to such
leases and cooperate with the Administrative Agent in all respects to cure any
such default, and cause each of the Subsidiaries to do so, except, in any case,
where the failure to do so, either individually or in the aggregate, could not
be reasonably expected to have a Material Adverse Effect.

         SECTION 5.13. Performance of Material Agreements. Perform and observe
all of the terms and provisions of the Stock Purchase Agreement and ancillary
agreements related thereto and each agreement that is material to the conduct of
the Borrower's and the Subsidiaries' business to be performed or observed by it
(collectively, the "Material Agreements"), maintain each such Material Agreement
in full force and effect, enforce such Material Agreement in accordance with its
terms, take all action to such end as may be from time to time requested by the
Administrative Agent and, upon request of the Administrative Agent, make to each
other party to each such Material Agreement such demands and requests for
information and reports or for action as Allied or the Borrower is entitled to
make under such Material Agreement, and cause each of the Subsidiaries to do so,
except, in any case, where the failure to do so, either individually or in the
aggregate, could not be reasonably expected to have a Material Adverse Effect.

         SECTION 5.14. Interest Rate Protection Agreements. As promptly as
practicable and in any event within 90 days after the Closing Date, enter into,
and thereafter maintain in full force and effect through the third anniversary
of the Closing Date, one or more Interest Rate Protection Agreements in form
reasonably satisfactory to the Administrative Agent, the Syndication Agent and
the Documentation Agent, the effect of which shall be to set at fixed rates the
interest cost to the Borrower and its Subsidiaries with respect to at least 50%
of the aggregate outstanding principal amount of Term Loans and AXELs Loans and
deliver evidence of the execution and delivery thereof to the Administrative
Agent, the Syndication Agent and the Documentation Agent.

         SECTION 5.15. Senior Convertible Debentures. Prior to the end of each
fiscal year, commencing with the fiscal year ending on December 31, 1997, the
Borrower shall deliver to the Administrative Agent evidence reasonably
satisfactory to the Administrative Agent that the Borrower will be in compliance
with the financial covenants of the Senior Convertible Debentures (including
compliance as a result of a waiver or amendment of the terms thereof), provided
that the Borrower shall not be obligated to deliver such evidence if prior to
any such fiscal year-end, the Borrower shall have prepaid all Senior Convertible
Debentures not converted prior to such prepayment, in each case in accordance
with the terms thereof.

         SECTION 5.16. Concentration and Disbursement Accounts. (a) Except to
the extent permitted by paragraph (b) below, the Borrower shall maintain with a
financial institution that is a Lender one or more accounts to be used by the
Borrower as its principal concentration and disbursement accounts and will not,
and will not permit any Subsidiary to, maintain more than an aggregate of
$1,000,000 for more than two Business Days in bank accounts with any person that
is not a Lender.

         (b) Notwithstanding the foregoing, paragraph (a) shall not apply to any
accounts of the Laidlaw Subsidiaries; provided, however, that with respect to
the accounts of the Laidlaw Subsidiaries that are Domestic Subsidiaries, (a) the
Borrower shall use its best efforts to be in compliance with paragraph (a)
within 180 days after the Closing Date and shall be in compliance with paragraph
(a) within 360 days after the Closing Date. The Borrower and the Subsidiaries
shall be deemed to be in compliance with this Section 5.16 at any time that a
lockbox arrangement in accordance with Section 4.09(b) of the Security Agreement
is in effect.

         Indebtedness"), which Indebtedness in each case exists at the time of
         such acquisition, merger, consolidation or conversion into a Subsidiary
         and is not created in contemplation of such event and where such

failure of or delay in performance or breach by any other Lender or the Issuing
Bank or the Borrower or any other Loan Party of any of their respective
obligations hereunder or under any other Loan Document or in connection herewith
or therewith. Each of the Agents may execute any and all duties hereunder by or
through agents or employees and shall be entitled to rely upon the advice of
legal counsel selected by it with respect to all matters arising hereunder and
shall not be liable for any action taken or suffered in good faith by it in
accordance with the advice of such counsel.

         The Lenders hereby acknowledge that no Agent shall be under any duty to
take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so by
the Required Lenders.

         Subject to the appointment and acceptance of a successor Agent as
provided below, any Agent may resign at any time by notifying the Lenders and
the Borrower. Upon any such resignation, the Required Lenders shall have the
right to appoint a successor. If no successor shall have been so appointed by
the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Agent gives notice of its resignation, then the retiring
Agent may, on behalf of the Lenders, appoint a successor Agent which shall be a
bank with an office in New York, New York, having a combined capital and surplus
of at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance
of any appointment as Agent hereunder by a successor bank, such successor shall
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent and the retiring Agent shall be discharged from its duties
and obligations hereunder. After the Agent's resignation hereunder, the
provisions of this Article and Section 9.05 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

         With respect to the Loans made by it hereunder, each Agent in its
individual capacity and not as Agent shall have the same rights and powers as
any other Lender and may exercise the same as though it were not an Agent, and
the Agents and their Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with Allied, the Borrower or any
Subsidiary or other Affiliate thereof as if it were not an Agent.

         Each Lender agrees to reimburse the Agents and each Revolving Credit
Lender agrees to reimburse the Issuing Bank, in each case, on demand, in the
amount of its pro rata share (based on its Commitments hereunder) of any
expenses incurred for the benefit of the Lenders by the Issuing Bank or the
Agents, as applicable, including counsel fees and compensation of agents and
employees paid for services rendered on behalf of the Lenders or the Revolving
Credit Lenders, as applicable, that shall not have been reimbursed by the
Borrower, and each Lender agrees to indemnify and hold harmless each Agent and
any of their respective directors, officers, employees or agents, and each
Revolving Credit Lender agrees to indemnify and hold harmless the Issuing Bank
and any of its respective directors, officers, employees or agents, in each case
on demand, in the amount of such pro rata share, from and against any and all
liabilities, taxes,

obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever that may be imposed
on, incurred by or asserted against it in its capacity as the Issuing Bank or
Agent, as applicable, or any of them in any way relating to or arising out of
this Agreement or any other Loan Document or any action taken or omitted by it
or any of them under this Agreement or any other Loan Document, to the extent
the same shall not have been reimbursed by the Borrower or any other Loan Party,
provided that no Lender shall be liable to the Issuing Bank or an Agent, as
applicable, or any such other indemnified person for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of the Issuing Bank or such Agent, as
applicable, or any of their respective directors, officers, employees or agents.

         Each Lender acknowledges that it has, independently and without
reliance upon the Agents or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon the Agents or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this Agreement or any other Loan Document, any related
agreement or any document furnished hereunder or thereunder.

representations and warranties made by the Borrower or Allied herein and in the
certificates or other instruments prepared or delivered in connection with or

                                                                              99





         (b) Each Lender may assign to one or more assignees all or a portion of
its interests, rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); provided,
however, that (i) except in the case of an assignment to a Lender or an
Affiliate of such Lender, (x) the Borrower (so long as no Event of Default shall
have occurred and be continuing) and the Administrative Agent (and, in the case
of any assignment of a Revolving Credit Commitment, the Issuing Bank and the
Swingline Lender) must give their prior consent to such assignment (which
consent shall not be unreasonably withheld or delayed) and (y) the amount of the
unused Commitment and Loans of the assigning Lender subject to each such
assignment (determined as of the date the Assignment and Acceptance with respect
to such assignment is delivered to the Administrative Agent) shall not be less
than $5,000,000 (or, if less, the entire remaining amount of such Lender's
Commitment) (it being understood that separate assignments that are made
contemporaneously to persons that are Affiliates shall be deemed a single
assignment for purposes of this sub-clause (y)), (ii) the parties to each such
assignment shall execute and deliver to the Administrative Agent an Assignment
and Acceptance, together with a processing and recordation fee of $3,500 and
(iii) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire. Upon acceptance and
recording pursuant to paragraph (e) of this Section 9.04, from and after the
effective date specified in each Assignment and Acceptance, which effective date
shall be at least five Business Days after the execution thereof, (A) the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement and (B) the assigning Lender thereunder shall, to
the extent of the interest assigned by such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Sections
2.14, 2.16, 2.20 and 9.05, as well as to any Fees accrued for its account and
not yet paid).

         (c) By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and the other parties hereto as follows:
(i) such assigning Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim and that
its Term Loan Commitment, AXELs Commitments and Revolving Credit Commitment, and
the outstanding balances of its Term Loans, AXELs Loans and Revolving Loans, in
each case without giving effect to assignments thereof which have not become
effective, are as set forth in such Assignment and Acceptance, (ii) except as
set forth in (i) above, such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement, or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement, any other Loan Document or any other instrument or
document furnished pursuant hereto, or the financial condition of the Borrower
or any Subsidiary or the performance or observance by the Borrower or any
Subsidiary of any of its obligations under this Agreement, any other Loan
Document or any other instrument or document furnished pursuant hereto; (iii)
such assignee represents and warrants that it is legally authorized to enter
into such Assignment and Acceptance; (iv) such assignee confirms that it has
received a copy of this Agreement, together with copies of the most recent
financial statements referred to in Section 3.05(a) or delivered pursuant to
Section 5.04 and such other documents and information as it has deemed
appropriate to make its own credit
<PAGE>   106
                                                                             100





analysis and decision to enter into such Assignment and Acceptance; (v) such
assignee will independently and without reliance upon the Administrative Agent,
the Syndication Agent, the Documentation Agent, the Collateral Agent, such
assigning Lender or any other Lender and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under this Agreement; (vi) such
assignee appoints and authorizes the Administrative Agent, the Syndication
Agent, the Documentation Agent and the Collateral Agent to take such action as
agent on its behalf and to exercise such powers under this Agreement as are
delegated to the Administrative Agent, the Syndication Agent, the Documentation
Agent and the Collateral Agent, respectively, by the terms hereof, together with
such powers as are reasonably incidental thereto; and (vii) such assignee agrees
that it will perform in accordance with their terms all the obligations which by
the terms of this Agreement are required to be performed by it as a Lender.

         (d) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive and the Borrower, the Administrative Agent, the Syndication Agent,
the Documentation Agent, the Issuing Bank, the Collateral Agent and the Lenders
may treat each person whose name is recorded in the Register pursuant to the
terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrower, the Issuing Bank, the Collateral Agent and any
Lender, at any reasonable time and from time to time upon reasonable prior
notice.

         (e) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) above and, if required, the written consent of the Borrower, the Swingline
Lender, the Issuing Bank and the Administrative Agent to such assignment, the
Administrative Agent shall (i) accept such Assignment and Acceptance, (ii)
record the information contained therein in the Register and (iii) give prompt
notice thereof to the Lenders, the Issuing Bank and the Swingline Lender. No
assignment shall be effective unless and until it has been recorded in the
Register as provided in this paragraph (e).

         (f) Each Lender may without the consent of the Borrower, the Swingline
Lender, the Issuing Bank or the Administrative Agent sell participations to one
or more banks or other entities in all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment
and the Loans owing to it); provided, however, that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) the participating banks or other entities shall be
entitled to the benefit of the cost protection provisions contained in Sections
2.14, 2.16 and 2.20 to the same extent as if they were Lenders and (iv) the
Borrower, the Administrative Agent, the Syndication Agent, the Documentation
Agent, the Issuing Bank and the Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, and such Lender shall retain the sole right to
enforce the obligations of the Borrower relating to the Loans

                                                                             101





or L/C Disbursements and to approve any amendment, modification or waiver of any
provision of this Agreement (other than amendments, modifications or waivers
decreasing any fees payable hereunder or the amount of principal of or the rate
at which interest is payable on the Loans, extending any scheduled principal
payment date or date fixed for the payment of interest on the Loans or
increasing or extending the Commitments).

         (g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower; provided that, prior to any such disclosure of
information designated by the Borrower as confidential, each such assignee or
participant or proposed assignee or participant shall execute an agreement
whereby such assignee or participant shall agree (subject to customary
exceptions) to preserve the confidentiality of such confidential information on
terms no less restrictive than those applicable to the Lenders pursuant to
Section 9.17.

         (h) Any Lender may at any time assign for collateral purposes only all
or any portion of its rights under this Agreement to a third party to secure
extensions of credit by such third party (or by persons on whose behalf such
third party acts) to such Lender; provided that no such assignment shall release
a Lender from any of its obligations hereunder or substitute any such third
party for such Lender as a party hereto. In order to facilitate such an
assignment, the Borrower shall, at the request of the assigning Lender, duly
execute and deliver to the assigning Lender a promissory note or notes
evidencing the Loans made to the Borrower by the assigning Lender hereunder.

         (i) Neither Allied nor the Borrower shall assign or delegate any of its
rights or duties hereunder without the prior written consent of the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Issuing Bank and each Lender, and any attempted assignment without such consent
shall be null and void.

         SECTION 9.05. Expenses; Indemnity. (a) The Borrower and Allied agree,
jointly and severally, to pay all out-of-pocket expenses incurred by the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, the Issuing Bank and the Swingline Lender in connection with
the syndication of the credit facilities provided for herein and the preparation
and administration of this Agreement and the other Loan Documents or in
connection with any amendments, modifications or waivers of the provisions
hereof or thereof (whether or not the transactions hereby or thereby
contemplated shall be consummated) or incurred by the Administrative Agent, the
Syndication Agent, the Documentation Agent, the Collateral Agent or any Lender
in connection with the enforcement or protection of its rights in connection
with this Agreement and the other Loan Documents or in connection with the Loans
made or Letters of Credit issued hereunder, including the fees, charges and
disbursements of Cravath, Swaine & Moore and Ogilvy & Renault, counsel and
Canadian counsel, respectively, for the Administrative Agent, the Syndication
Agent, the Documentation Agent and the Collateral Agent, and, in connection with
any such enforcement or protection, the fees, charges and disbursements of any
other counsel for the Administrative Agent, the Syndication Agent, the
Documentation Agent, the Collateral Agent or any Lender.

                                                                             102





         (b) The Borrower and Allied agree, jointly and severally, to indemnify
the Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, each Lender and the Issuing Bank, each Affiliate of any of the
foregoing persons and each of their respective directors, officers, employees,
trustees and agents (each such person being called an "Indemnitee") against, and
to hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses, including reasonable counsel fees, charges and
disbursements, incurred by or asserted against any Indemnitee arising out of, in
any way connected with, or as a result of (i) the execution or delivery of this
Agreement or any other Loan Document or any agreement or instrument contemplated
thereby, the performance by the parties thereto of their respective obligations
thereunder or the consummation of the Transactions and the other transactions
contemplated thereby (whether or not the Transactions are consummated), (ii) the
use of the proceeds of the Loans or issuance of Letters of Credit, (iii) any
claim, litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto, or (iv) any actual or alleged
presence or Release or threatened Release of Hazardous Materials on any Property
or any property owned, leased or operated by any predecessor of Allied, the
Borrower or the Subsidiaries, or any Environmental Claim related in any way to
Allied, the Borrower or the Subsidiaries; provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

         (c) The provisions of this Section 9.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the expiration of the Commitments, the expiration
of any Letter of Credit, the invalidity or unenforceability of any term or
provision of this Agreement or any other Loan Document, or any investigation
made by or on behalf of the Administrative Agent, the Syndication Agent, the
Documentation Agent, the Collateral Agent, any Lender or the Issuing Bank. All
amounts due under this Section 9.05 shall be payable on written demand therefor.

         SECTION 9.06. Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, except to the extent prohibited by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower or Allied against any of and all
the obligations of the Borrower or Allied now or hereafter existing under this
Agreement and other Loan Documents held by such Lender, irrespective of whether
or not such Lender shall have made any demand under this Agreement or such other
Loan Document and although such obligations may be unmatured. The rights of each
Lender under this Section 9.06 are in addition to other rights and remedies
(including other rights of setoff) which such Lender may have.

         SECTION 9.07. APPLICABLE LAW. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS (OTHER THAN LETTERS OF CREDIT AND AS EXPRESSLY SET FORTH IN OTHER LOAN
DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK. EACH LETTER OF CREDIT SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED IN ACCORDANCE WITH, THE LAWS OR RULES DESIGNATED IN SUCH LETTER OF
CREDIT, OR IF NO
<PAGE>   109
                                                                             103





SUCH LAWS OR RULES ARE DESIGNATED, THE UNIFORM CUSTOMS AND PRACTICE FOR
DOCUMENTARY CREDITS (1993 REVISION), INTERNATIONAL CHAMBER OF COMMERCE,
PUBLICATION NO. 500 (THE "UNIFORM CUSTOMS") AND, AS TO MATTERS NOT GOVERNED BY
THE UNIFORM CUSTOMS, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 9.08. Waivers; Amendment. (a) No failure or delay of the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, any Lender or the Issuing Bank in exercising any power or
right hereunder or under any other Loan Document shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Administrative Agent, the
Syndication Agent, the Documentation Agent, the Collateral Agent, the Issuing
Bank and the Lenders hereunder and under the other Loan Documents are cumulative
and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provision of this Agreement or any other Loan Document or
consent to any departure by the Borrower or any other Loan Party therefrom shall
in any event be effective unless the same shall be permitted by paragraph (b)
below, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. No notice or demand on the
Borrower or Allied in any case shall entitle the Borrower or Allied to any other
or further notice or demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower, Allied and the Required Lenders; provided,
however, that no such agreement shall (i) decrease the principal amount of, or
extend the maturity of or any scheduled principal payment date or extend the
date of any mandatory prepayment of principal, or date for the payment of any
interest on any Loan or any date for reimbursement of an L/C Disbursement, or
waive or excuse any such payment or any part thereof, or decrease the rate of
interest on any Loan or L/C Disbursement, without the prior written consent of
each Lender directly affected thereby, (ii) change or extend the Commitment or
decrease or extend the date for payment of the Commitment Fees or L/C
Participation Fees of any Lender without the prior written consent of such
Lender, (iii) decrease the amount or extend the date for payment of the Issuing
Bank Fees without the prior written consent of each affected Issuing Bank or
(iv) amend or modify the provisions of Section 2.13, 2.17 or 9.04(i), the
provisions of this Section, the definition of the term "Required Lenders" or
release any Guarantor or all or any substantial part of the Collateral, without
the prior written consent of each Lender; provided further that no such
agreement shall amend, modify or otherwise affect the rights or duties of the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, the Issuing Bank or the Swingline Lender hereunder or under
any other Loan Document without the prior written consent of the Administrative
Agent, the Syndication Agent, the Documentation Agent, the Collateral Agent, the
Issuing Bank or the Swingline Lender, respectively. Notwithstanding anything to
the contrary in this Agreement, any proposed waiver, amendment or modification
of a provision that does not directly affect each Class of Loans (as defined
below) shall require only the prior written consent of Lenders holding a
majority of the sum of all Loans outstanding and unused Commitments at such time
with respect to each Class of Loans directly affected thereby. As used in this
Section 9.08(b), the term "Class of Loans" shall mean each of (i) the Revolving
Credit
<PAGE>   110
                                                                             104





Loans and Revolving Credit Commitments, (ii) the Term Loans and Term Loan
Commitments, (iii) the AXELs Series A Loans and AXELs Series A Commitments, (iv)
the AXELs Series B Loans and AXELs Series B Commitments and (v) the AXELs Series
C Loans and AXELs Series C Commitments.

         SECTION 9.09. Interest Rate Limitation. Notwithstanding anything herein
to the contrary, if at any time the interest rate applicable to any Loan or
participation in any L/C Disbursement, together with all fees, charges and other
amounts which are treated as interest on such Loan or participation in such L/C
Disbursement under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan or participation in
accordance with applicable law, the rate of interest payable in respect of such
Loan or participation hereunder, together with all Charges payable in respect
thereof, shall be limited to the Maximum Rate and, to the extent lawful, the
interest and Charges that would have been payable in respect of such Loan or
participation but were not payable as a result of the operation of this Section
9.09 shall be cumulated and the interest and Charges payable to such Lender in
respect of other Loans or participations or periods shall be increased (but not
above the Maximum Rate therefor) until such cumulated amount, together with
interest thereon at the Federal Funds Effective Rate to the date of repayment,
shall have been received by such Lender.

         SECTION 9.10. Entire Agreement. This Agreement, the Fee Letters and the
other Loan Documents constitute the entire contract between the parties relative
to the subject matter hereof. Any other previous agreement among the parties
with respect to the subject matter hereof is superseded by this Agreement and
the other Loan Documents. Nothing in this Agreement or in the other Loan
Documents, expressed or implied, is intended to confer upon any party other than
the parties hereto and thereto any rights, remedies, obligations or liabilities
under or by reason of this Agreement or the other Loan Documents.

         SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.

         SECTION 9.12. Severability. In the event any one or more of the
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby (it being understood that
the invalidity of a particular provision in a particular jurisdiction shall not
in and of itself affect the validity of such provision in any other
jurisdiction). The parties shall endeavor in good-faith
<PAGE>   111
                                                                             105





negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

         SECTION 9.13. Counterparts. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original but all of which when taken together shall
constitute a single contract, and shall become effective as provided in Section
9.03. Delivery of an executed signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Agreement.

         SECTION 9.14. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 9.15. Jurisdiction; Consent to Service of Process. (a) Each of
Allied and the Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of any New York State
court or Federal court of the United States of America sitting in New York City,
and any appellate court from any thereof, in any action or proceeding arising
out of or relating to this Agreement or the other Loan Documents, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Administrative Agent, the Collateral Agent, the Issuing Bank or
any Lender may otherwise have to bring any action or proceeding relating to this
Agreement or the other Loan Documents against the Borrower, Allied or their
respective properties in the courts of any jurisdiction.

         (b) Each of Allied and the Borrower hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
the other Loan Documents in any New York State or Federal court. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by
law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 9.16. Judgment Currency. (a) The obligations of the Borrower
and the other Loan Parties hereunder and under the other Loan Documents to make
payments in dollars (the "Obligation Currency") shall not be discharged or
satisfied by any tender or recovery pursuant to any judgment expressed in or
converted into any currency other than the Obligation Currency, except to the
extent that such tender or recovery results in the effective receipt by the
Administrative Agent, the Syndication Agent, the Documentation Agent or a Lender
or the Issuing Bank of the full amount of the Obligation Currency expressed to
be payable to the
<PAGE>   112
                                                                             106





Administrative Agent, the Syndication Agent, the Documentation Agent or such
Lender or the Issuing Bank under this Agreement or the other Loan Documents. If,
for the purpose of obtaining or enforcing judgment against the Borrower or any
other Loan Party or in any court or in any jurisdiction, it becomes necessary to
convert into or from any currency other than the Obligation Currency (such other
currency being hereinafter referred to as the "Judgment Currency") an amount due
in the Obligation Currency, the conversion shall be made at the rate of exchange
(as quoted by the Administrative Agent or if the Administrative Agent does not
quote a rate of exchange on such currency, by a known dealer in such currency
designated by the Administrative Agent) determined, in each case, as of the date
immediately preceding the day on which the judgment is given (such Business Day
being hereinafter referred to as the "Judgment Currency Conversion Date").

         (b) If there is a change in the rate of exchange prevailing between the
Judgment Currency Conversion Date and the date of actual payment of the amount
due, the Borrower covenants and agrees to pay, or cause to be paid, as a
separate obligation and notwithstanding any judgment, such additional amounts,
if any (but in any event not a lesser amount), as may be necessary to ensure
that the amount paid in the Judgment Currency, when converted at the rate of
exchange prevailing on the date of payment, will produce the amount of the
Obligation Currency which could have been purchased with the amount of Judgment
Currency stipulated in the judgment or judicial award at the rate of exchange
prevailing on the Judgment Currency Conversion Date.

         (c) For purposes of determining the rate of exchange for this Section,
such amounts shall include any premium and costs payable in connection with the
purchase of the Obligation Currency.

         SECTION 9.17. Confidentiality. The Administrative Agent, the
Syndication Agent, the Documentation Agent, the Collateral Agent, the Issuing
Bank and each of the Lenders agrees to keep confidential (and to use its best
efforts to cause its respective agents and representatives to keep confidential)
the Information (as defined below) and all copies thereof, extracts therefrom
and analyses or other materials based thereon, except that the Administrative
Agent, the Syndication Agent, the Documentation Agent, the Collateral Agent, the
Issuing Bank or any Lender shall be permitted to disclose Information (a) to
such of its respective officers, directors, employees, agents, professional
advisors, affiliates and representatives as need to know such Information, (b)
to the extent requested by any regulatory authority, (c) to the extent otherwise
required by applicable laws and regulations or by any subpoena or similar legal
process, (d) in connection with any suit, action or proceeding relating to the
enforcement of its rights hereunder or under the other Loan Documents, (e) to
any direct or indirect contractual counterparties in swap agreements as long as
such contractual counterparty shall agree to keep such Information confidential,
(f) to the National Association of Insurance Commissioners or any similar
organization or any nationally recognized rating agency that requires access to
information about such Lender's investment portfolio in connection with ratings
issued with respect to such Lender or (g) to the extent such Information (i)
becomes publicly available other than as a result of a breach of this Section
9.17 or (ii) becomes available to the Administrative Agent, the Syndication
Agent, the Documentation Agent, the Issuing Bank, any Lender or the Collateral
Agent on a nonconfidential basis from a source other than the Borrower or
Allied. For the purposes of this Section, "Information" shall mean all financial
statements, certificates, reports, agreements and

                                                                             107





information (including all analyses, compilations and studies prepared by the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, the Issuing Bank or any Lender based on any of the foregoing)
that are received from the Borrower or Allied and related to the Borrower or
Allied, any shareholder of the Borrower or Allied or any employee, customer or
supplier of the Borrower or Allied, other than any of the foregoing that were
available to the Administrative Agent, the Syndication Agent, the Documentation
Agent, the Collateral Agent, the Issuing Bank or any Lender on a nonconfidential
basis prior to its disclosure thereto by the Borrower or Allied, and which are
in the case of Information provided after the date hereof, clearly identified at
the time of delivery as confidential. The provisions of this Section 9.17 shall
remain operative and in full force and effect regardless of the expiration and
term of this Agreement.


         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.
